Abstract

MICROWAVE SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL ACTIVITIES OF CuS AND CdS NANO PARTICLES

S. Priscilla Prabhavathi, Ranjith, Shameela Rajam,*Maruthamuthu, Johnson.T

ABSTRACT

The emerging need of CuS and Transition metal sulfides have numerous applications in various fields made its synthesis needful and meaning full. In recent years there is increasing interest in semiconductor nano crystals due to their novel physical and chemical properties. Most of these sulfides are crystalline and exhibit high lubricities. These features make these sulfides a far better photoluminescent material as compared to oxides. Many sulfides exhibit semi-metallic behavior with respect to the ability to form multiple oxidation states, thus they are applicable in microelectronics as semiconductor materials.The emerging need of Cd and CdS nanoparticles in the medicine and many other fields made its synthesis needful and meaning full. For example CdS is an important semiconductor and has many optoelectronic applications including Solar cells, photodiodes, light emitting diodes, nonlinear optics and heterogeneous photo catalysis. In the present study we have synthesized CdS nanoparticles of chemical precipitation technique. CdS is an important inorganic material for light-emitting applications. The literature survey showed that there are numerous methods to prepare Cadmium Sulfide (CdS) nanoparticles. To our knowledge, there is no report of synthesis of Cadmium sulfide nanoparticles by using SLS as a capping agent. So we have planned to synthesis the CdS nanoparticles by using SLS as a capping agent and to characterize the product by various analytical methods. Such The particles are characterized using FTIR, XRD, SEM, and Antimicrobial activity.

Keywords: Sulfides, Microwave, FT-IR, XRD, SEM, Anti-microbial activity.
