TLDR
Electronic energy transfer between close packed quantum dots using cw and time resolved photoluminescence is demonstrated and is consistent with long-range resonance transfer of electronic excitations from the more electronically confined states of the small dots to the higher excitedStates of the large dots.Abstract:
We demonstrate electronic energy transfer between close packed quantum dots using cw and time resolved photoluminescence. Optically clear and thin, close packed quantum dot solids were prepared from mixtures of small and large CdSe quantum dots (38.5 and 62 \AA{}, $\ensuremath{\sigma}l4.5%$). Quenching of the luminescence (lifetime) of the small dots accompanied by enhancement of the luminescence (lifetime) of the large dots is consistent with long-range resonance transfer of electronic excitations from the more electronically confined states of the small dots to the higher excited states of the large dots.read more

Control of optical properties in cyanine dye thin film fabricated by a layer-by-layer method
TL;DR: In this article, a layer-by-layer (LBL) method was proposed for the fabrication of cyanine dye molecule thin films, where the photoluminescence properties can be controlled by the separation between donor and acceptor dye molecule layers.

Self-Assembled Two-Dimensional Array of Gold Nanoparticles with Different Size for the Sensing Application
TL;DR: In this paper, a self-assembled two-dimensional array of gold nanoparticles (GNPs) on the glass substrate was systematically investigated in terms of glass cleaning, K2CO3 addition, GNP size, and pH of gold colloids.
Quantum Dot Nanobioelectronics and Selective Antimicrobial Redox Interventions
TL;DR: In this article, it was reported that superoxide radicals have been reported to occur from attack of the deoxyribose sugar leading to scission, though its greater impact lies in its ability to form.
