Increased Color-Conversion Efficiency in Hybrid Light-Emitting Diodes utilizing Non-Radiative Energy Transfer

ADVANCED MATERIALS, Issue 5 2010
Soontorn Chanyawadee
An efficient hybrid color-conversion light-emitting device consisting of colloidal nanocrystal quantum dots (NQDs) and a surface-patterned GaN-based LED is demonstrated (see figure). Excitation in a surface-patterned LED is efficiently transferred to NQD emitters via non-radiative energy transfer. A twofold enhancement of the NQD emission is achieved. [source]

Hybrid Inorganic/Organic Semiconductor Heterostructures with Efficient Non-Radiative Energy Transfer,

ADVANCED MATERIALS, Issue 3 2006
G. Heliotis
An inorganic/organic hybrid semiconductor heterostructure is reported, in which an InGaN quantum well is non-radiatively coupled to a semiconducting polymer overlayer (see Figure). This architecture has the potential to take advantage of the complementary attributes of the two types of semiconductor that it contains, and may lead to devices with highly efficient emission across the entire visible spectrum.

Probing the Contraction and Association of Polystyrene Chains in Semidilute Solution by Non-Radiative Energy Transfer

MACROMOLECULAR RAPID COMMUNICATIONS, Issue 2 2008

Abstract The interchain contraction and association of polystyrene in semidilute solution near the , temperature are studies using NET. The results reveal that during a drop of temperature, polystyrene chains pass through different states: a smooth change of conformation at temperatures above the , temperature, an accelerated contraction and association, aggregation of polymer chains, and then further continuous contraction below the , temperature. A pronounced hysteresis is observed during repeated heating. A viscosity study of the same solution was compared with the NET results. It indicates that NET can effectively be used to study conformational changes like contraction and association of polymer chains in a semidilute solution. [source]
