✦ Synopsis

Glow Curves of Flux-grown NaMgFI Crystals

Glow curves and optical absorption spectra of X-irradiated flux grown crystals are studied.

Two glow peaks at 370, 585 K and three shoulders at 420, 540 and 610 K are obtained.

Optical absorption studies reveal two absorption bands at 405 and 475nm and a well defined peak a t 295 nm. Room temperature annealing and bleaching studies have suggested that the glow peaks at 370 and 585 K may correspond to impurities and $-centers of 295 nm band respectively. The other shoulders a t 420, 540 and 610 K are attributed to other F-aggregate centers. The glow peaks are analysed using first order kinetics.
