基于Eu/Tb/SnO2纳米晶体共掺杂二氧化硅玻璃的三激活剂光致发光自参考光学温度测量
Triple-activator Photoluminescence of Eu/Tb/SnO2 Nanocrystals Co-doped Silica Glasses for Self-referencing Optical Temperature Measurement
摘要
Abstract
Self-referencing optical thermometers have shown competitive advantages on fast response and high ac-curacy as they can avoid inevitable external factors like concentration change,excitation fluctuation,and detector loss.Herein,we report the triple-emitting photoluminescence of Eu/Tb/SnO2 nanocrystals co-doped silica glasses.The temperature-dependent fluorescence intensity ratio of non-thermal coupled levels of Eu3+(5D0-7F2 transition,620 nm)/Eu2+(4f65d-8S7/2 transition,434 nm)and Eu3+(5D0-7F2 transition,620 nm)/Tb3+(5D4-7F5 transition,542 nm)can be used for self-referencing temperature probing in a wide range of 298-773 K.The maximum relative thermal sensi-tivity Sr values can reach 2.3%·K-1 at 773 K,which is higher than most Eu/Tb co-doped materials.This work will contribute a new Eu/Tb co-doped material to self-referencing optical temperature measurement with triple activa-tors.关键词
