Features of 172nm Excimer Lamp
Excellent Monochromaticity:The 172nm excimer lamp emits an extremely narrow ultraviolet wavelength range, only 172±10nm, enabling precise targeted irradiation and improving treatment effectiveness.
Concentrated Ultraviolet Output Energy: High ultraviolet output intensity, reaching up to 100mW/cm², allows for rapid and effective surface treatment of materials.
Incoherent Light: Beneficial for large-area processing, improving production efficiency.
No Electrode Corrosion: Compared to traditional light sources, the 172nm excimer lamp eliminates the electrode corrosion inherent in traditional light sources, significantly extending its lifespan to 1500-2000 hours (typical).
Instantaneous On/Off: Can be instantly turned on and off at any time, requiring no preheating or shutter; the number of on/off cycles does not affect lifespan.
Cold Light Source: Does not produce infrared output, exhibiting no significant heating effect on the treated object, avoiding thermal damage.
Environmentally Friendly: Manufacturing does not require mercury, eliminating secondary pollution and waste recycling issues, meeting environmental protection requirements.
Advantages of 172nm Excimer Lamp
Achieving Ultra-Low Gloss:
Precise gloss control in the 1-20 GU range optimizes light scattering through nano-scale surface modifications.
Anti-Fingerprint and Silky Touch:
The nano-structured surface repels fingerprints and provides a smooth, tactile finish.
Exceptional Durability:
Chemically bonded surface-modified layers provide high physical and chemical resistance, significantly enhancing scratch, solvent, and chemical resistance.
Cost Efficiency:
The process eliminates the need for matting agents, reducing raw material costs and simplifying production for improved productivity. VOC emissions are minimized, supporting environmental sustainability.
Applications of 172nm Excimer Lamp
Photocleaning: Utilizes deep ultraviolet light emitted from a 172nm excimer lamp to effectively remove organic contaminants and particles from substrate surfaces, achieving high-precision photocleaning and improving device performance.
Photocuring: Rapidly initiates the polymerization reaction of photosensitive materials, accelerating the curing process and shortening the production cycle.
Hydrophilic Modification: Uses ultraviolet energy to hydrophilically modify the surface of semiconductor devices, enhancing surface activity and improving device wettability and adhesion.
Pure Water Preparation and TOC Degradation: Effectively degrades total organic carbon (TOC) in water, reducing TOC content to ppb levels and ensuring water purity.
Liquid Crystal Display Device Manufacturing: Used for photolithography and surface modification to improve product yield.
Medical Device Sterilization: Utilizes ultraviolet light to destroy microbial DNA, achieving efficient sterilization and ensuring medical safety.
Scientific Research and Innovation: Supports research in photochemical reactions, coating matting treatment, and flexible material curing.
Other Fields: Such as plastic surface modification, UV curing, PDP phosphor analysis, and skin disease treatment.
Working Principle of 172nm Excimer Lamp
Break molecular bonds
The energy to break the molecular bonds of an organic substance requires light energy that exceeds the binding energy of the substance, and the greater the energy absorption (excitation) of the substance, the easier it is to initiate a reaction (decomposition) and the shorter the processing time required. Therefore, binding energies that cannot be broken using low-pressure UV lamps can be broken down using the 172 nm wavelength produced by excimer lamps.
Generates a large number of excited oxygen atoms
Compared with traditional mercury UV lamps, 172nm excimer UV lamps have the advantages of large light intensity, precise targeting, mercury-free manufacturing, green environmental protection, recyclability, and no secondary pollution. Compared with the 185nm wavelength of the low pressure UV lamp, the molecular oxygen absorption coefficient of the 172nm wavelength is about 20 times larger. This can not only generate high-density reactive oxygen species, but also generate strong excited oxygen with strong oxidative power by directly acting on oxygen.
Safety Protection
Personal Protection
Direct Exposure Risk
172nm ultraviolet light belongs to the vacuum ultraviolet (VUV) band, with photon energy as high as 7.23eV. It can directly break organic molecular bonds (such as the cellular structure of skin and eyes), leading to photokeratitis, skin burns, or cancer.
Protective Measures
When operating, you must wear UV-protective goggles (such as polycarbonate material, labeled UV400 protection) and protective clothing (long sleeves, gloves). Avoid direct eye contact with the light source; it is recommended to use a light shield or remote operation equipment. Warning signs must be posted in the operating area, and unauthorized personnel must be restricted from entering.
Environmental Safety
Ozone Generation
When 172nm ultraviolet light irradiates the air, it will excite oxygen to generate ozone (O₃). Excessive concentration may cause respiratory irritation or poisoning.
Control Measures
Install a ventilation system to ensure that the ozone concentration is below 0.1ppm (Chinese National Standard "Occupational Exposure Limits for Hazardous Factors in the Workplace"). When used in enclosed spaces, an ozone decomposition device (such as a catalytic filter) must be provided.
Maintenance
Lamp Lifespan
Typical lifespan: 700-2000 hours (affected by lamp material and temperature).
Replacement Criteria: Replace when output intensity decreases to 70% of initial value (can be monitored using a UV intensity tester).
Maintenance Cycle: Clean the lamp surface regularly (once a month, wipe with isopropyl alcohol) to prevent dust accumulation.
Component Inspection
External Electrodes and High-Voltage Components: For air-cooled compact lamps, check electrode connections for looseness every 6-12 months.
Cables and Interfaces: Ensure high-voltage cables are undamaged to prevent arcing.
Storage Conditions
Environmental Requirements: Store in a dry, dark place (humidity <60%), temperature 5-30℃.
Shock Protection: Avoid mechanical impacts to the lamp (drops may cause the quartz glass to break).
