Potassium-alumina-boron glass doped with copper ions for solar cell down-convertors

In the work borate glasses with additives of copper and fluorine is considered. The luminescence quantum efficiency of these glasses reaches 50 % in the visible range. Therefore the concerned borate glass is the promising material for solar cell down-convertors, sensitive elements of the spark sensors and UV detectors and as a cheap phosphor for warm-white LEDs. All that makes boron glass doped with copper ions promising for use in devices such as spark sensors, down-converters, cheap phosphors for white leds.
