We have successfully synthesized Sn 1− x Ni x O 2 (0.05 ≤ x ≤ 0.15) solid solutions in order to study their structural, optical, and magnetic properties at different Ni concentrations. X‐ray diffraction showed monophasic and crystalline tetragonal structure. The shifting of peaks toward higher angle is attributed to the incorporation of Ni 2+ ions in SnO 2 host lattice. Particle growth restrained upon Ni‐doping and found to be in the range of 8–12 nm. Ni‐doped SnO 2 nanoparticles show blue shift in band gap studies, which is found to be in the range of 3.9–4.1 eV. High surface areas have been achieved for these solid solutions, which come out to be 130, 200, 457, 497, and 680 m 2 /g, respectively. The solid solutions exhibit paramagnetic behavior along with antiferromagnetic exchange coupling.
