Information × Registration Number 0202U006284, 0101U006285 , R & D reports Title The investigation of photochemical coloration of large dimension NaI(Tl) single crystals used for large detector production.. popup.stage_title Head Shakhova K.V., Registration Date 20-06-2002 Organization Scientific-research department of alkali halide crystals with experimental manufacture STC "Institute for single crystals" NAS of Ukraine popup.description2 The determining role of oxygen is established during photochemical colouring of crystals Na (Tl), which basic source is the impurity, present in initial raw material, IO-3. The decomposition by last occurs to formation of oxygen in the melt Na during cultivation of crystals. Is established, that the additional presence at such crystals of residual impurity of lead results in stabilization of the centres of colouring, which is created under influence of day time light. The results are used in technology of reception of large-sized crystals Na (Tl) with scintilation properties, which are proof to influence of light.
