Preparation and properties of sol-gel thin film containing quinacridone latent pigment by using laser irradiation

Abstract

The synthesis of Ph-SiO2 film containing Qn-BOC latent pigment using the sol-gel method and the formation of thin film using laser irradiation have been investigated. The film is useful for a wavelength selective absorption film for displays and optical disk. Newly developed film formation technique using latent pigment and laser irradiation gives the excellent film having high transparency, excellent absorption characteristics and high durability. And also, this process is low cost process due to high speed film formation. © 2011 Ceramic Society of Japan.
