Abstract

Small GeO 2 single crystal was successfully grown on a polyvinyl chloride (PVC) substrate at room temperature in oversaturate aqueous solution. The oversaturated solution could be prepared at strong acid condition (pH~0) using distilled water, germanium oxide, dilute ammonia, and nitric acid. About 7 m size of the GeO 2 single crystals with quartz-type structure was obtained by only keeping the PVC plate in the solution for about 10 days when appropriate concentration of the solution was used. The obtained GeO 2 single crystals were confirmed to be constructed by {101} and {011} surfaces based on powder X-ray diffraction pattern and particle morphology observed by scanning electron microscope.
