%X SnO2 nanocrystals were synthesized, and their photoluminescence spectra revealed the following results. Firstly, we found that the main emission peak of the sample grown with catalyst-assistance is the emission peak of band gap (3.68 eV), and the photoluminescence efficiency of the crystal grown with catalyst-assistance is much higher than that without it. These results show that the quality of the crystal grown with catalyst-assistance is much improved. Furthermore, the emissions of twin-born crystal surfaces (101) and (101)T are demonstrated from the results of the deconvolution of photoluminescence spectra.
