Luminescent glass ceramic doped with multiple rare earth ions and capable of up and down-conversion to ultraviolet light and preparation method thereof

Abstract

The invention provides luminescent glass ceramic doped with multiple rare earth ions and capable of up and down-conversion to ultraviolet light and a preparation method thereof; the glass ceramic is fluorosilicate glass ceramic doped with at least four rare earth ions, wherein on a basis of oxide, the molar content of the rare earth ions is 1% to 20% of the total amount of the glass ceramic; the glass ceramic can realize up conversion of infrared light and visible light into ultraviolet light, and also realize down conversion of short-wave radiation into ultraviolet light.

Description

technical field

[0001] The invention relates to the field of solid luminescent materials, in particular to a rare earth-doped glass ceramic capable of simultaneously realizing up-conversion and down-conversion ultraviolet luminescence and a preparation method thereof. Background technique

[0002] In recent years, due to the important application prospects of ultraviolet laser in high-density optical data storage, optical display and infrared sensor, biomedicine and other fields, its acquisition method has attracted wide attention of material scientists. Converting long-wavelength laser to short-wavelength laser by up-conversion luminescent material is an effective method to obtain short-wavelength laser. Upconversion luminescence, also known as frequency upconversion luminescence, is a process in which radiative transitions are generated by multiphoton absorption, and the energy of the radiated photons is usually higher than that of the pump photons. Rare earth ion doping ...
