Creation of multiple optical functions based on structural control of inorganic luminescent materials

Abstract

Creation and introduction of multiple functions in inorganic luminescent materials can open new possibilities for applications other than conventional lighting and display technologies. This article reviews recent developments in the synthesis of multifunctional luminescent materials through chemical processing of ceramics. Particular emphasis is put on the structural control of materials to generate some interesting optical and chemical properties. The procedures and results are described for luminescent pigments consisting of core-shell-structured particles, antireflective luminescent coatings based on a bi-layer structure or a pseudo moth-eye structure, and redox-sensitive smart phosphors in the form of nanopowders and thin films.
