ABSTRACT
The visualization and control of optical to thermal energy conversion in nano and microstructures is a key challenge in many fields of science with applications to areas as nanofluidics, nanocatalysis, photothermal cancer therapy, drug delivery, imaging and spectroscopy, information storage and processing, nanoscale patterning and solar energy harvesting. In the presented work a polymer nanocomposite incorporated with silver nanoparticles and organic luminescence dye has been fabricated, which exhibits thermo chromic properties. It was shown that this kind of composite dramatically changes its color when changes an environmental temperature and acts as a thermo chromic material with such improved parameters as temperature controlled fine-tuning of absorption. This combination of silver nanoparticles and organic luminescent dyes can find versatile application in the areas such as: fabrication thermo addressable luminescence displays and thermo optical printers, environmentally friendly thermo chromic clothes. In medicine: modeling, simulation and visualization of heat spreading to the surrounding biological medium, new possibilities for measuring the heat release at the nanoscale, fabricating nano sized storage media for quantum information devices, thermo controllable filters, windows and smart coatings, infrared image converters. A simple technology promises to fabricate thermo chromic material based cost-effective devices.
