Title: Intrinsic high magnetism in SnO{sub 2} quantum dots

High magnetic moment was observed in SnO{sub 2} quantum dots (QDs) which were prepared by a soft chemical method. SnO{sub 2} QDs were characterized for morphological, structural and optical properties using high resolution tunneling electron microscopy and photoluminescence (PL) spectroscopy, respectively. Magnetism occurred in QDs SnO{sub 2} due to dominant oxygen defects, were studied using PL measurements.
