Abstract
- Solid-state scintillation materials reach a pick of their popularity and one of such attractive materials is the new Gd3Al2Ga3O12:Ce single crystal with unique and promising scintillation properties. The fundamental optical properties of this crystal and the effect of the composition deviations on them are studied poorly. This investigation is focused on the estimation of the influence of the Al to Ga partial substitution in the Gd3Al5-xGaxO12 cationic sublattice on the transmission spectra and refractive indices. In this work transmission spectral dependences and the refractive indices dispersion dependences were obtained by spectrophotometric methods using certified methods on calibrated equipment. The effect of the cationic substation on the transmission spectra is weak, slight decrease in intensity of Al:Ga ration 3:2 samples was observed in the wavelength region 200-350 nm. In the studied wavelength range 200-700 nm refractive index values of the crystals with an Al to Ga ratio 3:2 are lower than values of the crystals with a 2:3 ratio. [ABSTRACT FROM AUTHOR]
