  Structural and Optical Study of CdSe Q-dots

  By Jyotsna Chauhan, Varsha R. Mehto, Akanksha Mehto, Priyanshita Thakur

  Abstract: In this paper we have report the properties of CdSe Q-dots. Calculations of different parameters for different sizes of CdSe Q-dots are presented. The XRD analysis used to find the composition, crystal structure and crystallite size. Scherrer equation is used to calculate the Nano crystallite size. XRD analysis reveals that the CdSe QD crystallite sizes in the sample are 3.26 nm, 3.72 nm, and 3.20 nm by applying the appropriate …

  Synthesis & Characterization of Bimetallic Nanoparticles by Using PVP for Magnetic Storage Device

  By Jyotsna Chauhan, Varsha R. Mehto, Sumit Tiwari

  Abstract: Metal nanoparticles are broadly studied due to their unique chemical and physical properties, which differ from the properties of their respective bulk materials. Bimetallic nanoparticles (BNPs) are formed by the combination of two different metals. Bimetallic nanoparticles have attracted huge attention in fields such as magnetic sensors, catalysts, optical detection and biomedical applications because of their exceptional properties. In this work bimetallic nano particles have been synthesized by using a …

  Synthesis and Characterization of CdS Nanoparticles for LED Application

  By Jyotsna Chauhan, Varsha R. Mehto, Dharmendra Kumar

  Abstract: In the present work we have synthesized the size tuned CdS nanoparticles with chemical routes method. Size of the nanoparticle tuned with varying the addition of an appropriate quantity of capping agent. UV spectroscopy used to study the variation of optical properties with tuning the size of nanoparticle. EMA and TBM techniques are used to analyze size and band gap of the quantum dots.
