Er3+ doped lead-halide crystals perform a number of properties which make them perspective for practical use in waveguides and spectrum converters. In current work we have studied luminescence spectra dependencies over the excitation wavelength, luminescence intensity dependences over temperature for up-conversion excitation of most significant lines (530, 550 and 650 nm) under 980 nm excitation. Luminescence decay kinetics under 313 nm and 365 nm excitation in KPb2Cl5:Er3+, RbPb2Br5:Er3+ и KPb2Cl5:Er3++Yb3+ have been measured and theoretical estimates of the lifetimes were made in accordance with Judd-Ofelt technique. Received results can be used in laser systems design and for accuracy evaluation when Judd-Ofelt technique for these crystals is applied.
