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

Abstract The compositions of 3 wt.% trivalent erbium ions (Er 3+ ) doped zinc silicate (Zn 2 SiO 4 ) 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.%Er 3+ :Zn 2 SiO 4 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 Er 3+ ions are located at 492 nm ( 4 F 7/2 ), 524 nm ( 2 H 11/2 ), and 650 nm ( 4 F 9/2 ). The intensive sharp characteristic emission that correlated with Er 3+ 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.
