Title: Fluorescence Decay Characteristics of the Green Emission From CaF2:Ho3+
Author: Sudha Kartha,C; Ramachandran, T; Nampoori, V P N; Sathianandan, K
Abstract: Variations in the decay times of the characteristic green emissions at 522.7, 551.3, 549.6, 547.6, 542.2, 540.2, 535.9 and 533.5nm from CaF2 :H03+ with concentration are studied at RT and LNT. A pulsed N2 laser beam of power density 1.5 MW cm-2 is used for the excitation. Temperature dependent concentration quenching of the decay times are observed for all the emission bands. But an increase in the decay time due to the reabsorption process is also observed for a few of the above bands.
