Preparation and Characterization of Rare Earth Doped Ba0.65 Zr0.35 F2.70 Up-conversion Nanocrystals
摘要
Abstract
Nanocrystalline up-conversion phosphor Ba0.65 Zr0.35 F2.70 : Er3+ , Yb3+ were prepared by hydrothermal method using EDTA as complexing agent. The phase transformation, structure and morphology of the sample were analyzed by XRD and TEM, and the grain size of the sample was 20-40 nm. The sample has most intense upconversion luminescence when the mole ratio of Yb3+: Er3+ is 4:1. The relationship between up-conversion relative intensity and pump power was also studied, and revealed that the luminescence peaks of 523 nm, 546 nm and it's 650 nm were all two-photon process.关键词
