Electron Microscopy Analysis of CdSe-CdS Quantum Dot-in-Rods Coated Mimosa pudica Fibre

Abstract:

Semiconducting polymer based X-ray detector design is quite interesting and challenging task for the researchers. Because of low X-ray attenuation of polymers, the device becomes insensitive. In the paper we report a way through the introduction of fluorescent nanoparticles to increase the X-ray detection probability.The Mimosa pudica fibre was coated with CdSe-CdS quantum dot-in-rods on the surface by chemical dipping processes. The fibre morphology and microstructure have been analysed by TEM and SEM techniques. The well-oriented CdSe-CdS quantum dot-in-rods have been observed in TEM with an aspect ratio (rod length ̸ rod diameter) of 28.7×3.5 nm and quantum yield 78% of a sharp emission peak at 545 nm. The CdSe-CdS quantum dot-in-rods coated M. pudica fibre, as observed in SEM, possesses a honeycomb structure of the nano-material. It is expected that the interaction between static-electric field of the fibre and the field produced by the above quantum particle causes to form a well-ordered honeycomb cover on the fibre of the surface. The goal of this study is to confirm the feasibility of the X-ray imaging detection system based on the quantum size effect on coated conducting fibre.
