Recent advances in rare earth co-doped luminescent tungsten oxygen complexes

Abstract

Rare earth (RE) materials have been employed in almost every corner of modern industry, such as lighting applications, defense technology, and industrial catalysis. Particularly, RE-based tungsten oxygen complexes have been intensively studied across academia and industry for their easy manufacturing, high stability and low cost, and more interestingly, novel optical properties. To date, some novel multi-RE tungsten oxygen complexes in various aggregation states and morphologies have been synthesized and investigated in several fields. In this review, we will talk about the synthesis and characterization of RE co-doped tungsten oxygen complex materials, related luminescent mechanism studies, optical properties and applications of these complexes, with the aim of the further development of new materials for optical and biological applications.
