Abstract
The luminescent properties of erbium(III)-doped fluorozirconate glass and fluorozirconate phosphate glass and glass ceramics containing NaPO3 were compared. The glasses were obtained by rapid melt quenching and were characterized using luminescence spectroscopy, differential thermal analysis, x-ray diffraction, and transmission electron microscopy. When NaPO3 was added, the relative luminescence intensity of Er(III) in the near infrared (NIR) region doubled at 1530 nm (4I13/2 → 4I15/2 transition). The luminescence intensity of other bands in the visible and NIR regions decreased. Luminescence quantum yields and lifetimes of the studied samples were measured. The reasons for the change in luminescence intensity after addition of NaPO3 and heat treatment of the samples were discussed.
