Photoluminescent Siloxenes in Nanoporous Aluminum Oxide

Abstract

Light-emitting silicon systems are of interest both scientifically and technologically. Luminescence can arise either from silicon structures or from siloxene-like systems. The formation of photoluminescent siloxenes by spontaneous decomposition of silanes in the channels of aluminum oxide membranes is reported, which opens up simple novel routes to stable light-emitting systems. The advantages of using nanoporous aluminum oxide membranes are discussed, the presence of siloxene layers on the pore surfaces is proved, and the photoluminescence data are presented.
