Germanium oxide (GeO2) nanoparticles with a narrow size distribution have been synthesized by a reverse micelle technique. The cubic GeO2 particles with particle size of 15 nm were obtained as the reaction solution was left standing for 24 h, the particle size and shape can be controlled by changing the molar ratio of surfactant/water (R) and the aging time. The effect of Rw and aging time on the particle size was discussed.
