Abstract
Pyrochlores Bi1.6HoxTi2O7 – δ and Bi1.6Mg0.1Ho xTi2O7 – δ, where x = 0, 0.01, 0.05, and 0.1, and Bi1.5HoxTi2O7 – δ, where x = 0.25 and 0.5, have been synthesized and their structural, optical, and luminescence properties have been studied. As a result of analyzing the data obtained experimentally and the available theoretical data, it is shown that the intrinsic luminescence of the samples is due to the O2p ↔ Bi6p and Bi6s ↔ Bi6p electron transitions and the impurity luminescence is due to the f–f transitions in Ho3+ and the O2p → Ho3+ charge transfer.
