Abstract
Strontia nanoparticles are successfully prepared by chemical precipitation method. The SrO nanoparticles are characterized by XRD, UV-DRS and I-V analysis. X-ray diffraction peaks reveal the single-phase polycrystalline tetragonal structure with preferential orientation along (2 0 2) direction. Influence of annealing temperature strongly induce the growth of peak which indicates the increased intensity of (202) peak. The heat treatment strongly distresses the growth of triplet peaks (002), (101) and (110) whereas the same augment the growth of (202) and (310). Strontium oxide nanoparticles would allow more light for absorption in UV region due to its rough surface whereas the same would allow moderate light absorption in visible region due to its high packing density. The expansion and contraction of Sr-O bonds leads to a high crystalline nature with its purity at 322 nm. It is proposed that strain and surface defects in SrO nanocrystal take place due to different absorption edge.

Strontium oxide nanoparticles are extensively used in the cathode ray tube industry, in which they are employed in the form of aluminum alloy to shield humans from X-ray emissions from the traditional color television [3,4,5,6]
Summary
Metal oxides play a very important role in many areas of chemistry, physical and materials science. The research in the area of nanostructured metal oxides; gradually gather popularity for their remarkable properties in electronic, magnetic, optical, thermal and mechanical domains [1]. Among these metal oxides, Strontium is an alkaline earth metal and its oxide Strontia (SrO) is a strongly basic oxide. SrO is electronically conductive and has been used in solar cell, fuel cell, gas sensors, and cathode materials in the solid oxide form as an oxygen generation system. Nanosized SrO materials with welldefined particle morphology and size shows an excellent optical, thermal, high oxidation resistance, high mechanical, electric, chemical inertness and magnetic properties. An attempt has been made to prepare Strontium oxide nanoparticles and investigate their structural, optical and electrical properties
