摘要

The new glasses in the ZnNbOF5-BaF2-ErF3 system were synthesized. The main factor determining the thermal characteristics and structure of glasses is the oxyfluoroniobate component, erbium trifluoride has a modifying effect only. When glasses are heated to 500 °C, the glasses with containing erbium trifluoride from 0.1 to 3 mol% are transformed into glass ceramics. By changing the amount of erbium trifluoride in the glasses in the ZnNbOF5-BaF2-ErF3 system, the process of obtaining glass ceramics can be controlled. The glasses in the ZnNbOF5-BaF2-ErF3 system show luminescence properties, corresponding to the transitions: 4S3/2 → 4I15/2 (543 nm), 2H11/2 → 4I15/2 (550 nm), 4F9/2–4I15/2 (660 nm). The luminescence intensity increases synchronously with ErF3 content in the range of 0.1–1 mol% and at further increase in the content of ErF3 in the glass composition leads to a gradual decrease in the luminescence intensity from concentration quenching. The appearance of crystalline phases in the glasses leads to a noticeable decrease in the luminescence intensity.
