Abstract
Lanthanide-doped optical functional glasses have received substantial attention in recent years owing to their excellent upconversion (UC) and infrared (IR) performance pumping when used in a semiconductor laser. In this study, the luminescence properties of ions were improved through the design of components used to modulate the microenvironment of the glass. To the best of our knowledge, this is a novel approach to enhancing the UC and IR emissions, and results in up to more than 130% improvement by regulating a tight network glass structure. Herein, the specific preparation design and investigations into the thermal, structural and luminescence properties are described, the results of which indicate that such ZnO-modified germanosilicate (SG-Zn) multicomponent glasses are promising candidates in the fields of biological security marking, optical communication, and 3D volumetric displays.
