Abstract

CaNb2O6:Yb, Er, Ho phosphors are prepared by a solid-state reaction. The optical properties, X‑ray diffraction (XRD) patterns, and luminescence mechanism of the phosphors are discussed. The samples are found to be single phases. The CaNb2O6:Yb, Er, Ho phosphor has IR emission under 940-nm excitation. Its IR luminescence spectrum consists of four bands with maxima at 1010, 1200, 1540, and 2070 nm. Energy transfer between activators is observed and analyzed via luminescence properties. The optimal concentrations of CaNb2O6:xYb, yEr, zHo phosphor at which the maximum luminescence intensity is achieved in the region of 2 μm are x = 15 mol %, y = 7 mol %, and z = 1 mol %.

CaNb2O6:Yb, Er, Ho 的红外发光特性

摘要

CaNb 2 O 6 :Yb、Er、Ho 荧光粉通过固态反应制备。讨论了荧光粉的光学性质、X 射线衍射 (XRD) 图案和发光机制。发现样品是单相。CaNb 2 O 6 :Yb、Er、Ho 磷光体在 940 nm 激发下具有 IR 发射。其红外发光光谱由四个波段组成,最大值分别为 1010、1200、1540 和 2070 nm。通过发光特性观察和分析活化剂之间的能量转移。CaNb 2 O 6的最佳浓度:x Yb, y Er, z在 2 μm 范围内实现最大发光强度的 Ho 磷光体为x = 15 mol %、y = 7 mol % 和z = 1 mol %。
