Technical Data: Modification of Sol-Gel Films by Vacuum Ultraviolet Light Irradiation

Measurement of ultraviolet and visible light transmission spectrum using a spectrophotometer! Introduction to the modification of sol-gel thin films.

The sol-gel method, which is a promising approach to obtaining coatings with uniform composition, typically requires heat treatment at several hundred degrees Celsius to remove moisture from the gel film and to decompose organic components. Therefore, it is challenging to obtain a strong film on plastics with low heat resistance. In this context, the vacuum ultraviolet (VUV) light-based photon process can be considered applicable for modifying thin films, as it can break atomic bonds solely through the action of photons without accompanying thermal processes from irradiation. This document introduces the changes in state when VUV light is irradiated onto nickel oxide thin films adjusted by the sol-gel method, using an excimer lamp developed as a practical light source.
