The approaches to the synthesis of promise up-and down-conversion luminescence materials

Modern flexible and technological methods for synthesis of promise luminescent materials in the form of nano- and ultrafine powders, ceramics, and glass ceramics with effective up- and down conversion luminescence are proposed. The use of compounds of various compositions and combinations of activator ions in them ensures the effective conversion of IR and UV radiation into the visible region of the spectrum. Using various approaches to the synthesis and their combinations allows you to widely vary the structure and properties of the materials. The proposed materials are promising as visualizers of infrared radiation, multi-color phosphors, and conversion-luminescent laser materials.
