Spectral and luminescent characteristics of La1-xPrxGa0.5Sb1.5O6, Bi1-xPrxGe0.5Sb1.5O6 (x = 0 - 0.5) solid solutions.

Recently, a lot of research has focused on the search for high-performance phosphors with high quantum yield. Compounds with a rosiaite structure are proposed as a promising matrix for phosphors. Due to the structural features of rosiaites, the distance between neighboring RE ions is ≥5 Å, which reduces the probability of concentration quenching. This paper presents the results of a comparative analysis of the spectral-luminescent properties of La1-xPrxGa0.5Sb1.5O6, Bi1-xPrxGe0.5Sb1.5O6, (x = 0.01, 0.05, 0.1, 0.25, 0.5) solid solutions.
