摘要：

Three types of Pr-activated phosphors are studied: those with predominant 5d-4f transitions, those with transitions from the P-3(0)-level, and those with successive transitions from the S-1(0)- and P-3(0)-levels of 4f-configuration. The theoretical-model analysis of a photon cascade emission (PCE) is carried out. The basic properties of host matrixes necessary for PCE detection are ascertained. The spectral and kinetic (luminescence decay) characteristics of a number of Pr-activated oxides and fluorides are measured. SrAlF3:Pr is found to exhibit the best luminescent properties among the phosphors studied. The host matrixes for the continued search for the PCE effect are suggested.
