Abstract
- The effects of selective components M 2 O 3 (M=Al, Ga) on local structure, thermal and spectroscopic properties of lead phosphate glasses doped with Er 3+ ions were systematically investigated. It was found that the both oxide modifiers (Al 2 O 3 and Ga 2 O 3 ) may be classified as crystallizing agents for lead phosphate glass host. The glass transition temperatures for glass samples modified by M 2 O 3 were determined using differential scanning calorimetry. The X-ray diffraction analysis was used in order to verify the nature of lead phosphate - based systems. Near-infrared luminescence spectra corresponding to 4 I 13/2 → 4 I 15/2 transition of erbium ions were measured. The luminescence spectra of Er 3+ -doped lead phosphate glass are presented and discussed in relation to the impact of crystallizing agents M 2 O 3 (M=Al, Ga). Luminescence lifetimes for the upper 4 I 13/2 laser state of Er 3+ ions were also evaluated. [ABSTRACT FROM AUTHOR]
