Abstract

Bright white up conversion emission has been observed in sol–gel derived Yb³⁺/Er³⁺/Tm³⁺: Y₂SiO₅ nanocrystalline powders when excited with the 950 nm emission of a laser diode. Measurements of the sample emission intensity dependence on the pumping power were performed to explain the up conversion mechanism. The CIE chromaticity coordinates (x, y) for white emission in X2–Y₂SiO₅ nanocrystalline form were found to be (0.334, 0.332) under 950 nm laser diode excitation.
