Identification of point defects on Co-Ni co-doping in SnO${}_2$ nanocrystals and their effect on the structural and optical properties

S. Roy, Brijmohan Prajapati, A. Singh +3

Sn${}_{0.97-y}$Co${}_{0.03}$Ni${}_y$O${}_2$ (0 $\le y\le$ 0.04) nanocrystals, with average crystallite size in the range of 7.3 nm ($y$=0.00) to 5.6 nm ($y$=0.04), have been synthes…
