Structural, Optical and Electrical Characterization of CdSe Nanorods Synthesized by Solvothermal Process

الملخص EN

CdSe nanorods are synthesized by solvothermal process in a mixed solvent of hydrazine hydrate [H6N2O], ammonia [NH3] and deionized water.

Cadmium acetate [(CH3COO)2Cd·2H2O] and sodium selenite [Na2SeO3] are used as precursors for cadmium and selenium ions, respectively.

FESEM is used to study the morphology of the synthesized nanorods.

XRD measurement shows wurtzite phase of CdSe.

SAED pattern and TEM measurement are also used to study the structure and morphology of the particles.

UV-Vis_NIR measurement shows strong absorption around 730 nm.

Nanorods thin films are prepared using doctor blade technique.

Conductivity of the thin film samples is measured in vacuum using two-probe method.
