We report here the synthesis and characterisation of nano-sized silicon germanium oxide (SiGeO) nanoparticles with mole ratio of Si:Ge being 1:1 via liquid mix and sol-gel techniques. The SiGeO nanoparticles were characterised via x-ray diffraction, high resolution transmission electron microscopy, field emission scanning electron microscopy and photoluminescence spectrophotometry. The SiGeO nanoparticles were found to have hexagonal crystal system with intense (101) reflections. The morphology studies indicated that the nanoparticles are spherical in shape with diameter ranging from 10 - 35 nm and clustered in nature. Quantitative photoluminescence examination indicated that Si0.5Ge0.5O2 produced via liquid mix technique had significant photoluminescent characteristics with λmax centering at about 430 nm.
