Efforts were made to see effort of sodium hydroxide amount of different properties of the materials thus three sample were synthesized with different amount of sodium hydroxide precursors. The as-prepared sample was characterized by X-Ray diffraction (XRD), field emission scanning electron spectroscope study. Also the samples were characterized further with the help of Fourier-Transformed infrared (FTIR) spectroscopic study as well as Raman Spectroscopic study taken in reflection mode. XRD conforms the proper Phase formation of the sample whereas the microscopic analysis has given an idea about the morphological as well as dimensional information. FTIR study gives the information regarding the different bonding present in sample. Reflection study shows that, due to the change in the precursor amount, there is a marked difference in the reflection spectra as well as optical gap of the sample.

INTRODUCTION Nano scale metal oxide materials have been attracting much attention because of their unique size- and dimensionality- dependent physical and chemical properties as well as promising applications as key components in micro/Nano scale devices. Cupric oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors. Copper oxide is a semiconductor material and has a natural abundance of starting material (Cu). It is non-toxic and easily obtained by the oxidation of Cu. Copper oxide is one of the important metal oxide which has attracted recent research because of its low cost, abundant availability as well as its peculiar properties. It is used in the fields like catalysis, superconductors, ceramics as a kind of important inorganic materials etc. CuO has been used as a basic material as the superconductivity in these classes of systems is associated with Cu-O bonding. Among all metal oxide nanoparticles, copper oxide has gained the most interest because of its wide applications, such as in solar cell technology, field emission, magnetic storage media, lithium ion batteries, gas sensing, drug delivery, magnetic resonance imaging, and field emission devices. Applications CuO first attracted attention of chemists as a good catalyst in organic reactions but recently discovered applications of CuO such as high-Tc superconductors, gas sensors, solar cells, emitters, electronic cathode materials also make this material a hot topic for physicists and materials science engineers. Some of the most interesting applications of CuO Nanomaterial’s are sensing, photo catalyst, and super capacitor. CuO Nano-materials have wide range of applications in the several fields i.e. In very first huge application in electrical and electronics devices. Super-capacitors and Electrodes for Lithium Ion Batteries Sensing Applications Photo catalyst and Solar Energy Conversion Field Emission Effect [6] EXPERIMENTAL Materials Copper chloride (Cu), Sodium hydroxide (NaOH) and Ultrapure Deionized (DI) water and ethanol. All materials were purchased and used without further purification. Synthesis procedure CuO nanostructure was synthesized by precipitation method using copper chloride (Cu). First. Copper chloride was dissolved in 100 ml deionized water to form (0.1M) concentration, NaOH solution (0.1M) was slowly dropped under vigorous stirring until pH reached to 10, 12 and 14 respectively, So there are three different precursor ratio are taken i.e. pH10, pH12 and pH14. Black precipitates were obtained and repeatedly, washed by ultrapure deionized water and absolute ethanol sequentially added till pH reached [7]. Subsequently, the washed precipitates were dried at 80 °C for 16 h.
