Modulation of phosphor luminescence performance by high concentration self-sensitization of Er and Ho–Yb ion co-doping under 1550 nm excitation

Abstract

In this paper, upconversion fluoride phosphors NaY1-x-y-zF4:Er3+x, Ho3+y, Yb3+z were synthesized by the low-temperature combustion method. And the optimal ratio of lanthanide ion doping in the matrix lattice was determined...
