Layer-by-Layer Assembly of Colloidal CdS and ZnS−CdS Quantum Dots and Improvement of Their Photoluminescence Properties

Autor: Shinya Okahara, Masaaki Nakayama, DaeGwi Kim, Kunio Shimura

Publikováno v: The Journal of Physical Chemistry C. 113:7015-7018

Thin films of colloidal CdS and ZnS−CdS alloy quantum dots (QDs) were fabricated by layer-by-layer (LBL) self-assembly to synthesize blue luminescent QD thin films. The assembly of negatively charged colloidal QDs and positively charged poly(dially

We investigated the influence of methylviologen (MV 2+ ), which accelerates the photoetching process used for controlling size distribution, on the photoluminescence (PL) properties of colloidal CdS quantum dots (QDs). A combination of the photoetchi

Experimental verification of Förster energy transfer between semiconductor quantum dots

Autor: YongGu Shim, Masaaki Nakayama, Shinya Okahara, DaeGwi Kim

Publikováno v: Physical Review B. 78

In recent years, energy transfer (ET) using semiconductor quantum dots (QDs) is getting increased attention. However, it has been postulated that ET between QDs is based on the F\"orster model, which is a well-established model of ET mechanism in org
