Advanced red phosphors for white light-emitting diodes
Junhao Li,Jing Yan,Dawei Wen,Wasim Ullah Khan,Jianxin Shi,Mingmei Wu,Qiang Su,Peter A. Tanner +7 more
TL;DR: In this article, a review summarizes recent achievements concerning red phosphors mainly from three aspects: intensifying absorption bands and reducing lattice defects to increase quantum efficiency; selecting an appropriate coordination environment and altering the lattice symmetry to fine-tune the luminescence spectra; and reducing the nonradiative transition rate and preventing charge imbalance of a luminecence centre to enhance thermal stability.
