Optical properties of (organic polysilane)–(inorganic matrix) hybrid thin films

Abstract Polysilane–inorganic hybrid thin films – organic polysilane embedded in a silica matrix – were fabricated using a sol–gel method to improve the durability of organic polysilanes as optoelectric devices. Photoluminescence measurements at 10 K show that the durability against ultraviolet light exposure is improved in the polysilane–inorganic hybrid thin films. In addition, the luminescence linear polarization memory is found at 10 K, suggesting the decrease in the interchain interaction of polysilanes in the polysilane–inorganic hybrid thin films.
