Abstract

Recent years have witnessed the development of first-principles approaches to study luminescent properties of rare-earth ions and point defects in inorganic phosphors. In this article， we briefly describe the progresses made by the authors and co-workers in this field. Firstly， the first-principles-based approaches to rare-earth luminescent materials are introduced. These include density functional theory calculations of point defects based on the supercell model and wavefunction-based multi-configuration

ab initio

calculations of excited states. Then， the applications of the methods to some Ce

- and Eu

-doped phosphors are elaborated from two aspects，

i.e

.， thermodynamic stabilities and luminescence mechanisms of point defects， and assignment of 4f→5d excitation spectra of the doped rare-earth ions. Finally， chances and challenges in the field of first-principles calculations on rare-earth luminescent materials are briefly discussed.
