Probing quantum dot cores, their interfaces and thiol cappings non-destructively in dilute solution using Raman scattering in hollow core photonic crystal fiber

摘要

Efficient Raman scattering of thiol-capped CdTe quantum dot solutions were obtained using HC-PCF. Strong Raman modes of the CdTe core, thiol agents, and their interfacial compound were observed and compared for the first time.
