Synthesis and luminescence properties of Sr2ZnMoO6: Eu2O3 phosphors

Abstract

Abstract The Sr(2-x)ZnMoO6 phosphors doped with Eu2O3 were produced through the sintering process in the electrical furnace at a temperature of 1100 °C for 6 hours in an air atmosphere. The characteristics of the synthesized phosphors, including their photoluminescence properties and lifetime profile analysis, were investigated, along with their structure using X-ray diffraction analysis (XRD) and FTIR analysis. The crystalline structure of the Sr2ZnMoO6 phosphor was confirmed by a Rigaku SmartLab SE X-ray diffractometer (XRD). The phosphors doped with Eu3+ exhibited excitation bands at various wavelengths, including 362, 380, 394, 415, 465, 525, and 531 nm, and emitted light at 613 nm. The 465 nm was used for excitation, and the emission spectra displayed peaks at 590, 613, 652, and 699 nm, as measured by a Cary-Eclipse spectrofluorophotometer. The highest peak was observed at 613 nm, corresponding to 5D0 →7F2 (reddish-orange) transitions of the Eu3+ ion. The fluorescence decay time system (HORIBA Scientific) measured the decay time of the Eu3+ ion from the transition of 5D0 to 7F2 level. The decay time of phosphors was decreased with increasing the concentration of Eu2O3, which had a decay time of 0.453 to 0.340 ms when monitored at λex = 465 nm. The results obtained in photoluminescence properties. The results suggest that obtained photoluminescence properties of Eu2O3 doped Sr2ZnMoO6 phosphors have potential applications in optoelectronics.
