摘要：

Pristine and Pr-doped CaSnO3(CSO) nanostructures prepared by the chemical precipitation method are studied for optical and magnetic properties. Structural studies with lattice parameter variation and defect-related parameters arising on the effect of Pr ions are being investigated. Morphological changes from the doping concentration are described. Luminescence characteristics and bandgap variation are calculated from the optical properties. The presence of free radicals and anisotropic spin resonance centers are presented from EPR spectra. The magnetization behavior of pristine and Pr-doped CSO is explained through the defects and its related interaction with the host sites.
