Tunable and white light generation in lanthanide doped novel fluorophosphate glasses

Abstract

Fluorophosphate glasses have attracted increasing attention due to their superior structural and optical properties such as mediated phonon energy, good chemical and thermal stability, wide transmittance window, and providing a long lifetime for the radiative emissions of the rare earth ions. Therefore, the aim of this chapter is to present a general portrait of the current achievements and challenges on the preparation and properties of the rare earth ions doped fluorophosphate glasses. The chapter starts by reviewing the fundamentals of glasses, presenting the advantages of fluorophosphate glasses which are followed by spectroscopic formulation of the rare earth ions. Finally, several examples of the new fluorophosphate glasses doped with rare earth ions are presented and their spectroscopic and structural properties are discussed. Co-doped lanthanide ions doped fluorophosphate glasses are nominated as good candidates as white light generating or color tunable solid state materials.
