| Реферат: | eng: Alkali halide crystals doped with Er3+ exhibit several properties that make them promising for practical use in optical fibers and converters of the emission spectrum. In this work, we studied the luminescence spectra of crystals as a function of the excitation radiation wavelength and the temperature dependences of the luminescence intensity in the up-conversion mechanism of excitation of the most intense lines (530, 550, and 650 nm) and upon excitation at 980 nm. In KPb2Cl5:Er3+, RbPb2Br5:Er3+, and KPb2Cl5:Er3+ + Yb3+ crystals, the luminescence kinetics were measured upon excitation at 313 and 365 nm, and the theoretical estimates of lifetimes were made using the Judd-Ofelt theory. The results can be used in the development of laser-based systems and for estimating the degree of approximation of calculations by the Judd-Ofelt method for these crystals.
