Graphical Abstract
A study of the energy transfer in the composite system given by ZnO particles interacting with the conjugated polymer, poly[2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene], by varying the acceptor concentration, and the system temperature in the range 50–300 K is presented. The temperature dependence of the energy transfer rate is described by a rate model and a dipole–surface interaction scheme in the hybrid material.
Abstract
Determining and controlling the inter-component excitation conversion in light-emitting nanocomposite materials is a key factor for predicting the composite luminescence properties and for the operation of many opto-electronic devices. Here we present an extensive study of the inter-component energy transfer in the composite system given by ZnO particles interacting with the conjugated polymer, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]. The composite emission is studied upon varying the acceptor concentration, and the system temperature in the range 50–300 K. The temperature dependence of the energy transfer rate is described by a rate model, taking into account the temperature dependence of the single components nonradiative decay rates, and a dipole–surface interaction scheme in the hybrid material. The proposed model accounts very well for the experimental observation of energy transfer and can be used to predict the temperature behavior of the emission from light-emitting nanocomposite materials.
