Abstract
Herein, we report the synthesis of SnO 2 nanoparticles by combustion method using two reducing agents. One with urea as a fuel (SnO 2U) and another one with A z a d i r a c h t a i n d i c a leaves extract as a reducing agent (SnO 2N) and calcined at 500 oC for 3 hrs. The synthesized samples are characterized using different techniques. The Bragg reflections confirms the formation of pure tetragonal SnO 2 NPs. The surface morphological analysis clearly indicates the formation of irregular shaped agglomerated NPs. The agglomeration and particle size was found to be more in SnO 2U NPs. The estimated direct energy bandgap using Tauc`s relation was found to be 3.75 and 3.37 eV for SnO 2U and SnO 2 N respectively. Further, Photoluminescence excitation, emission, CIE and CCT analysis was performed. Thus, the present sample might be used as a nanophosphor material in Cool and Warm blue light emitting diodes. The cytotoxic properties against HeLa and MCF7 cells and compared the percentage of viability and cell death with standard chemotherapy drug Cisplatin. Theoretically, X-ray/gamma ray absorption properties such as mass attenuation coefficient (MAC) SnO 2U and SnO 2 N NPs were evaluated which might finds an application in nuclear radiation dosimetry.
