G. Ramalingaiah, R.P.Vijayalakshmi, K.Sunil Kumar , M. Ramanadha, A. Sudharani "Doping-Concentration-Induced Ferromagnetism and photoluminescence emission in CdS: Mn nanoparticles", International Journal of Engineering Trends and Technology (IJETT), V49(1),5-10 July 2017.

Pure and Mn doped CdS semiconductor nanoparticles (NP’s) were successfully synthesized by chemical method. The synthesized nanoparticles were subjected to X-ray Diffraction (XRD), EDAX, FTIR, SEM, Photoluminescence and VSM Studies. The structure of CdS and Mn doped CdS from XRD studies is cubic. The excitation wavelength in photoluminescence studies is 340 nm, green and red emissions were observed. The Vibrating sample magnetometer (VSM) studies explores that higher concentration of Mn (7.5%) doped CdS nanoparticles exhibited ferromagnetism.
