Abstract

PbSe nanocrystals doped with poly ethyleneglycol (PEG) were prepared using hydrothermal method. The reflectance spectra (R) were measured for these samples, and also refractive index (n) values were calculated, which increase with PEG ratio. Both of (Ed) and (Eo) increase with PEG content, while (N/m*) ratio decreased with PEG content. While all of (M-1), (M-3) and static refractive index (no), were determined. (ε\) and (ε\\) peak position decrease with photon energy (hν). Also both of (σ1) and (σ2) decrease with (hν), while (χ(1)) increases with (hν) for all samples. The nonlinear optical parameters such as, (n2) and (χ(3)) decrease with PEG, as a result of increasing the sample density with PEG. (βc), were determined theoretically. Both electrical susceptibility (χ(e)) and relative permittivity (ε(r)) has blue shift with (hν) for all samples. (Nc/ m*e (cm-3)), (Nv/m*h (cm-3)) were calculated theoretically.
