Approach for Selection of a Synthesis Procedure of GeO 2 Ultra-small Nano Particles and Its Characterization

A rigorous study of germanium oxide nano-particle synthesis is done by hydrothermal method. An optimum synthesis condition to obtain the stable and ultra-small size as of 10 nm of the material is determined by characterizing the prepared samples with X-Ray diffraction pattern analysis and TEM. The sample with smallest particle size is also characterized with HRTEM, PL and FTIR spectroscopy. The characterization results are analyzed accordingly. The most remarkable feature of the ultra small sized sample as observed is the current-voltage characteristic, which has been explained with oxygen vacancy phenomenon.
