Abstract

In this paper, the sol-gel synthesis and characteristic properties of mixed-metal oxides Y3ScxAl5-x-yGayO12 (0 ≤ x, y ≤ 5) having garnet crystal structure are reported. The polycrystalline powders were characterized by powder X-ray diffraction analysis (XRD), energy dispersive X-ray (EDX) analysis, IR spectroscopy and optical transmission measurements. Single-phase oxides Y3Sc1Al3Ga1O12, Y3Sc2Al1Ga2O12, Y3Sc2Al3O12 and Y3Al3Ga2O12 have been synthesized at 1000 °C. The transmittance spectra of Y3ScxAl5-x-yGayO12 samples were measured at room temperature in the range of 200 – 1200 nm.
