Luminescence of the Te4+ ion in ZrP2O7 (original) (raw)

Journal of Solid State Chemistry, 1989

Abstract

ABSTRACT The luminescence spectra and decay times of the Te4+ ion in ZrP2O7 are reported and discussed. ZrP2O7:Te4+ shows a blue emission band with a maximum at 21,200 cm-1 at LHeT. Decay time measurements reveal the presence of at least two kinds of Te4+ ions. This is not apparent from the luminescence spectra, indicating that the Te4+ ions have quite similar environments. The 1S0 --> 3P1 excitation band of the Te4+ ion is situated at 38,250 cm-1. A comparison is made with the luminescence of related systems.
