微腔中CdSe量子点荧光增强效应
Photoluminescence enhancement of colloidal quantum dots embedded in a microcavity
摘要
Abstract
We report on the study of CdSe quantum dot microcavity formed between two distributed Bragg reflectors (DBRs).The active region consisting of CdSe quantum dots is embedded in PMMA.We use the transfer matrix method (TMM) to simulate the reflectivity spectrum of the microcavity.We demonstrate an enhancement of the spontaneous emission from the colloidal CdSe quantum dots in the microcavity.After embedding the QDs in the cavity,the full width at half maximum (FWHM) is narrowed to 7.5 nm compared with 27.9 nm of QDs in free space.The emission of the quantum dots is enhanced by a factor of 3.7 due to the microcavity effect.关键词
