Abstract: (6056 Views)
In this paper Pb1-xSnXS nano Structur particle were synthesized by chemical precipitation method at room temperature under N2 atmosphere. Optical absorption and optical emission were studied by UV- visible spectrophotometer and photoluminescence spectroflurimeter respectively. Structural properties of samples were investigated by X- ray diffraction (XRD). XRD spectra shows that nanoparticles with cubic structure are formed, which increases with increasing of Sn concentration. The optical absorption spectra of the samples indicates that ban gap energy of the samples increases with increasing Sn concentration. PL spectra shows that all Sn doped samples have two emission peaks in visible region.
