Popis:	Two sets of CaWO4:Nd:Na crystals have been grown having Nd concentrations of 0.5 and 1.0 at.%, and various concentrations of Na. The photolytic coloring is somewhat enhanced by the presence of Na, whereas reduction coloring is made much more difficult by full compensation of the Nd with Na. The 2.9‐eV absorption for the extraordinary ray becomes more prominent with increasing Na content, in the case of reduction coloring. The atomic model applicable is discussed. Practical applications of these findings are also mentioned.
