报告摘要：

Transparent glass ceramic doped with active rare-earth ions is an advanced composite material composed of a glassy matrix and the precipitated (or inserted) nano/micro-crystals incorporated with active ions. This material is expected to integrate the advantages of optical features from the nano/micro-crystals and mechanical/chemical properties from the oxide glass. In this decade, such novel optical materials with excellent frequency conversion characteristics, i.e., up-conversion, quantum cutting down-conversion or down-shift emissions, had attracted increasing scientific interests in the field of functional materials, stimulated by their wide potential applications in the industry areas of light emitting diode, laser-driven lighting/display, photovoltaic solar cell, as well as optical storage medium, and so on. In recent years, my group is dedicated in systematic investigations of the property-directed design, synthesis, structure modification, and frequency conversion performance as well as the related potential applications of a serious of rare-earth doped inorganic composite glass ceramics, placing extra emphases mainly on searching the routes to achieve high luminescent quantum efficiencies, revealing the physical mechanisms dominating optical performances, and establishing structure-property relationships of the composite materials. This presentation introduces some of our main progresses achieved in these aspects, and discusses several prospective applications of the newly developed glass ceramic materials.
