Synthesis and characterization of one dimensional semiconducting nanorods and nanobelts

CdSe nanorods, nanobelts are synthesized via a simple sacrificial template assisted solvothermal route at a moderate temperature of 180°C. The influences of introducing sacrificial template, hydrazine hydrate (N 2 H 4 ·H 2 O) as the reducing agent, ammonia (NH 3 ·H 2 O) and NaOH as the complexing ag...

Description
Summary:CdSe nanorods, nanobelts are synthesized via a simple sacrificial template assisted solvothermal route at a moderate temperature of 180°C. The influences of introducing sacrificial template, hydrazine hydrate (N 2 H 4 ·H 2 O) as the reducing agent, ammonia (NH 3 ·H 2 O) and NaOH as the complexing agent on the morphology and size of the obtained CdSe nanorods and nanobelts are investigated and reported. CdSe nanorods with a mean diameter and length of 25 nm and 82 nm respectively are synthesized and the problem of handling the stacking faults present in the long CdSe is analyzed. The structural phase, morphology and the optical properties of CdSe nanorods and nanobelts are studied using powder X-ray diffraction, TEM/HRTEM, UV-visible absorption spectroscopy and photoluminescence (PL) spectroscopy respectively.
