Synthesis and green luminescence of low cost Er2O3 doped zinc silicate glass-ceramics as laser materials

The compositions of 3 wt.% trivalent erbium ions (Er3+) doped zinc silicate (Zn2SiO4) glass-ceramics was fabricated from waste materials via conventional solid-state method. From the XRD and FESEM results designate that the diffraction peaks of 3 wt.%Er3+:Zn2SiO4 glass-ceramics improved with the heat treatment progression and homogeneously distributed in hexagonal and rectangular shapes. From UV-vis measurement, three detected peaks of optical absorption that corresponding to the optical transitions of Er3+ ions are located at 492 nm (E-4(7/2)), 524 nm (H-2(11/2)) , and 650 nm (F-4(9/2)). The intensive sharp characteristic emission that correlated with Er3+ luminescence is resolved in photoluminescence spectra at room temperature and gives a yellow green light colour emission at 559 nm under 385 nm excitation peaks.
