Abstract

Novel Er3+ doped highly transparent glass-ceramics containing orthorhombic KLu2F7 nanocrystals (24 nm in diameter) have been successfully fabricated for the first time. Their structural, optical and upconversion properties are systematically investigated by XRD, TEM, absorption spectra, upconversion spectra and lifetime measurements. Excited by 980 nm laser, characteristic emissions of Er3+ are detected in all samples. Impressively, the upconversion luminescence of Er3+ is drastically enhanced (1340 and 680 times for green and red emissions, respectively) after crystallization. Laser power dependence of the upconverted emissions and upconversion decay curves were explored to understand the different upconversion mechanisms in precursor glasses and glass-ceramics. Results show that the enrichment of Er3+ into KLu2F7 lattice after crystallization is responsible for the enhanced upconversion.
