FULL-COLOR SIMULATION IN A MULTI-DOPED GLASS AND CONTROLLED QUENCHINGOF LUMINESCENCE USING ER(III) AS A SUPPRESSOR FOR A TUNABLE DEVICE

We have developed a multi-doped glassy material (CaF2-B2O3-Sb2O3) to g enerate and control the primary light colors, allowing the simulation of any color of light by additive synthesis, Tm(III), Tb(III) and Eu(I II) ions were used (0.01-5.0 mol%) as blue, green and red narrow line emitters, A wide color gamut was obtained under ultraviolet excitation by changing the material composition, The chromaticity diagram is cov ered, including the white simulation. We have proposed a mechanism to control the chromaticity of a fixed composition of the material, using the Er(III) ion (0.05-3.0 mol%) as a quencher which may be deactivate d by infrared excitation, The first results using Er(III) in our white emitter glass are presented.
