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 obtain coatings with uniform composition, typically requires heat treatment at several hundred degrees Celsius to remove moisture from the gel film and decompose organic components. This makes it difficult to obtain a strong film on low-temperature-resistant plastics. Therefore, 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.
