The luminescence of AgBr and AgBrCl crystals doped with Pr3+ rare-earth ions was investigated in the visible and infrared spectral ranges. We measured the excitation, emission, and absorption spectra as well as the kinetic parameters over a broad temperature range. The strong influence of the silver halide composition on Pr3+ ions spectroscopic properties was revealed. We calculated useful optical parameters for Pr:AgBr crystals by using the Judd–Ofelt approximation. Good agreement between the theoretical and the measured parameters was obtained.
