Description

The luminescent method of terbium determination in thulium oxides applying mixed crystallophosphors based on thulium-gadolinium oxyfluoride has been developeded. The direct proportionality between luminescence intensity and terbium content is observed from 2x10-5 up to 2.5x10-2 % of Tb2O3 in Tm2O3. The terbium content in Tmsub(0.1)Gdsub(0.9)OF crystallophosphors is calculated from the formula of the method of additions. Three specimens of thulim oxides were analyzed. The relative normal deviation changes over the range of 0.034-0.079 at n=10
