Optical properties of lanthanide-based pyrophosphate phosphor materials

Abstract

This chapter covers the synthesis, compositional effect and optical properties of lanthanide-based pyrophosphate phosphor materials. The general properties of the pyrophosphate materials have been discussed. The structural parameters of pyrophosphate phosphor materials have approved that these materials are very promising and thermally stable. Additionally, the energy transfer between the lanthanide ions has been discussed by taking some examples. Basically, the two ions are involved in the energy transfer in which former one is called as donor ion whereas latter one is the accepter ion. The energy transfer takes place from donor to acceptor ions. This leads to an enhancement in the photoluminescence intensity of different phosphor materials. The addition of some surface modifiers also enhances the photoluminescence intensity of the phosphor materials. The applications of lanthanide-based pyrophosphate phosphor materials have been also incorporated in this chapter. © 2020 Nova Science Publishers, Inc.
