Augustine, S. Mathew, C. Girijavallabhan, P. Radhakrishnan, V. Nampoori, M. Kailasnath] Here we report a facile one-pot method for the preparation of high-quality CdSe nanoparticles (NPs) in aqueous solution under an air atmosphere using reflux. CdSe nanoparticles with tunable optical absorption and highly luminescent emission spectra of the size 4.6nm-5.1nm samples are discussed. Dual beam mode-matched thermal lens technique has been employed to study the effect of heat diffusion in the size series of CdSe nanoparticles. It is found that thermal diffusivity of 0.63 ×10−3cm2/s, decreases with the increase in size of the CdSe nanoparticles. This change in thermal diffusivity makes the material for novel thermal applications. Characterization of the nanoparticles have done with TEM, SEM and XRD.
