Red, green and blue light generation in fluoride glasses controlled by double excitation

A new multi-doped fluoroaluminate-based glass was developed to generate, with high accuracy, the three primary light colors simultaneously, allowing additive synthesis of light in the visible spectrum. The ions Er 3+ and Tm 3+ were used as red, green and blue narrow line emitters, by down-conversion...

Description
Summary:A new multi-doped fluoroaluminate-based glass was developed to generate, with high accuracy, the three primary light colors simultaneously, allowing additive synthesis of light in the visible spectrum. The ions Er 3+ and Tm 3+ were used as red, green and blue narrow line emitters, by down-conversion and up-conversion processes. The Tm 3+ and Er 3+ concentrations in the glass were defined for simulation of the white emission, under double excitation in the infrared and ultraviolet region, allowing color tuning.
