Abstract Transparent Nd3+-doped GeO2 bulk gels and glasses were prepared by the sol-gel method, and their thermal and spectroscopic properties including electron spin resonance (ESR), absorption, fluorescence and upconversion fluorescence spectra were investigated. Absorption spectra characteristic of Nd3+ ions were clearly observed. Under 805 nm laser excitation, the glass showed upconversion fluorescence at 362, 389, 421, 430, 470, 534, 600, and 662 nm at room temperature.
