496-500 The development and luminescence properties of (0.2 mol <span style="mso-bidi-font-family: Arial;mso-bidi-language:HI">%) of Eu3+ and Tb3+ ions doped borophosphate oxyfluoride (BPOF) optical glasses have been reported in the following general compositions: 69.8 B2O3.10 P2O5-10 <span style="mso-bidi-font-family:Arial; mso-bidi-language:HI">(ZnO/CdO/TeO2)-10 (A1F3/LiF) Measured emission spectra of Eu3+: BPOF optical glasses have revealed five emissions (5D0→7F0.1.2.3&4) at 580, 591, 613, 654 and 701 nm, respectively with λexci = 392 nm (7F0→5L6). In case of Tb3+: BPOF optical glasses, four emissions (5D4→7F6,5,4&3) that are located at 489, 545, 584 and 622 nm have been measured with λexci = 374 nm. For the red (Eu3+) and green (Tb3+) emission bands, decay curves have been recorded to compute their lifetimes. By using relevant energy level diagrams, emission processes in the glasses have been explained.
