Abstract:
β-NaYF4 : Dy3+ transparent glass-ceramics with high luminous efficiency were successfully prepared by melt quenching method.The control of the luminescence spectrum and photo-temperature sensing properties of β-NaYF4 : Dy3+ glass-ceramics by doping noble metal Ag was investigated. The relationship between the fluorescence intensity,fluorescence intensity ratio,temperature sensitivity and other parameters with temperature was obtained under the excitation of 355 nm.This research provides a new method for temperature measurement in the teaching process of university physics experiments.
