Abstract

A novel Tm3+/Er3+/Yb3+ triply-doped glass ceramics containing BaF2 nano-crystals are successfully prepared. Fluoride nanocrystals BaF2 are successfully precipitated in glass matrix, which is affirmed by the X-ray diffraction results. The intense blue (476 nm), green (543 nm), and red (656 nm) emissions of the glass ceramics are simultaneously observed at room temperature under 980-nm excitation, and the emission luminescence intensity increases signiˉcantly compared with the precursor glass, which is attributed to the low phonon energy of °uoride nanocrystals when rare-earth ions are incorporated into the precipitated BaF2 nanocrystals. Under 980-nm excitation at 400 mW, the international commission on illumination (CIE) chromaticity coordinate (X = 0.278, Y = 0.358) of the tridoped oxy°uoride glass ceramics' upconversion emissions is close to the standard white-light illumination (X = 0.333, Y = 0.333). The results indicate that Tm3+/Er3+/Yb3+ triply doped glass ceramics can act as suitable materials for potential three-dimensional displays applications.
