Abstract
Optical properties of Pr3+ ions in lead-free germanate glasses modified by BaF2 were investigated. Luminescence bands related to 3P03H4, 3P03H5, 1D23H4, 3P03H6, 3P03F2 transitions of Pr3+ were registered under 450 nm excitation. The relative integrated luminescence intensities of 3P0 → 3H4 transition (blue) to the 3P03F2 transition (red) of Pr3+ ions strongly depend on fluoride modifier BaF2 in glass composition. The blue-to-red luminescence intensity ratios of Pr3+ are drastically reduced, when BaO is partially substituted by BaF2. The luminescence lines due to 3P03F2 hypersensitive transition of Pr3+ are blue shifted with increasing BaF2 concentration.
