Fluorescence blinking statistics from CdSe core and core/shell nanorods

Article Abstract:

An analysis of measurements of fluorescence blinking from single CdSe nanorods (NR) of seven varying sizes with wide range aspect ratio from 3 to 11 is reported and the observations are compared the observations with the measurements of blinking statistics from spherical CdSe core and CdSe/ZnS core/shell nanocrystals (NCs). It was found that the off-time probability distributions are described by a power law and the on-time probability distributions by a truncated power law both for NRs and spherical NCs and the degree of quantum confinement maybe in some extent responsible for the aspect ratio dependence of the crossover time.

Growth and luminescence of ternary semiconductor ZnCdSe nanowires by metalorganic chemical vapor deposition

Article Abstract:

Study is conducted to show that ZnCdSe nanowires can be grown by metalorganic chemical vapor deposition (MOCVD) using Au as a catalyst. The presence of an Au-Cd-Zn alloy particle at the tip of the nanowires support vapor-liquid-solid as the growth mechanism while the appearance of constrictions in some of nanowires is found to be linked to the existence of structural defects, possibly stacking faults, during growth.

Aqueous-organic phase-transfer of highly stable gold, silver, and platinum nanoparticles and new route for fabrication of gold nanofilms at the oil/water interface and on solid support

Article Abstract:

A simple but effective-organic phase-transfer method for gold, silver, and platinum nanoparticles is developed on the basis of the decrease of the poly(N-vinylpyrrolidone)'s (PVP's) solubility in water with the temperature increase. It is observed that the shapes and sizes of gold nanoparticles as the building blocks may be controllable through changing reaction conditions.
