Abstract

Generation of the color-tunable reddish to magenta upconversion luminescence in Tm^3 +-single-doped glasses under near-infrared (1.1 to 1.3 μm) excitation is reported. Upconversion emission in the ultraviolet, blue- and red-spectral regions due to D₂1-H₆3, D₂1-F₄3, G₄1-H₆3, G₄1-F₄3, and F_2,33-H₆3 transitions, respectively, was observed. The dependence of upconversion emission upon excitation power and Tm^3 + content was also investigated. Adjusting the excitation power and Tm^3 + concentration, the overall fluorescence emission can be tuned across the reddish to magenta color in the international commission on illumination color chromaticity diagram. The CIE-1931 color coordinates move from red toward the bluish region occupying the magenta region with an increase in the excitation power.
