Photoluminescence study of Er-doped zinc-sodium-antimonite glasses
Original language description
Bulk samples of Er-doped zinc-sodium-antimonite glasses have been investigated by transmission and photoluminescence (PL) spectroscopy. Two series of compositions, (Sb2O3)(90) (x)(Na2O)(10)(ZnO)(x) and (Sb2O3)(80) (x)(Na2O)(20)(ZnO)(x), doped with 0.25 mol% Er2O3, have been chosen for this study. Transmission spectra exhibit sharp absorption bands centred at 450, 489, 521, 545, 652, 795, 975 and 1530 nm, which correspond to absorption of Er3+ ions and they are attributed to the optical transitions fromthe ground state I-4(15/2) to the excited states F-4(5/2), F-4(7/2), H-2(11/2), S-4(3/2), F-4(9/2), I-4(9/2), I-4(11/2) and I-4(13/2), respectively. The optical gap has been found to vary from 3.09 to 3.15 eV with a tendency to decrease at higher Na2O and/or ZnO contents. Four extrinsic bands due to OH, Si-O, CO2, and (CO3)(2) carbonate group vibrations have been identified in the infrared region. Emission spectra are overwhelmed by narrow 4f-4f emission bands.
