The luminescence and energy transfer processes in La 2 O 3 -Nb 2 O 5 -B 2 O 3 :M 3+ (M=Bi, Eu, Dy) glasses were investigated using luminescence spectroscopy (excitation and emission, down to 4.2K) and decay time measurements at room temperature. The observation of niobate luminescence implies a considerable degree of short- and intermediate-range...
Photo-luminescence studies of Pr 3+ activated thorium oxide phosphor have revealed that mainly 3 P-> 3 H 4 and 1 D 2 -> 3 H 4 transitions with life-time of 30 and 600μs are observed in this sample. An exponential reduction in the emission intensity of Pr 3+ ions was observed on following continuous excitation with...
