Sažetak

Photoluminescent properties are studied of boric phosphor of 2-phcnylquinoline by investigating its fluorescence and phosphorescence spectra, phosphorescence intensity and its decrease with time at different temperatures. The phosphorescence decreases with time according to the exponential law. The luminescence spectrum of this phosphor activated by the light of 313 nm is composed of two components which correspond to the transitions between the states of the same and different multiplet. The change of phosphorescence intensity with temperature is found to obey the Mott-Seitz formula.
