The Effect of Time Ageing of Spray-Deposited on the Growth of CdSe Nanoparticles

Abstract

Cadmium Selenide (CdSe) was obtained by using spray-deposited method which is using the sodium selenosulfite as Se precursor and cadmium chloride (CdCI) as cadmium (Cd) precursor. Time for each spray-deposited was used as the main parameter to investigate the properties of CdSe nanoparticles. By using FESEM for surface morphology and X-ray Diffraction (XRD) studies reveal that the CdSe nanoparticles with cubic crystal structures. In this research, the effect of time of spray deposited was main parameter to know the CdSe properties. The set of time was set from 10 min until 50 min. From FESEM result the size of CdSe nanoparticles were in the range 60-70 nm and the crystalline was hexagonal from XRD result. By using Scherrer equation, the size of crystalline of CdSe nanoparticles was determined from XRD characterization, the size was 60-70 nm. The size of CdSe nanoparticles from FESEM images were 60-80nm.
