Various nonlinear regimes of stationary emission of crystal phosphors with several types of impurity centers are investigated. In the case of two types of centers (radiative and nonradiative recombination), general equations are derived which connect the emission yield with the volume density of the excitation, given the temperature and the parameters of these centers. The degree of nonlinearity K and the temperature sensitivity RT are obtained for various ratios of the parameters of the centers and for definite ranges of excitation conditions. The conditions needed to obtain anomalously high values of K and R T are established, and their limiting values upon saturation of the effective nonradiative-recombination centers are estimated. The diverse roles of the quenching processes in practical applications of crystal phosphors is discussed. |
