Abstract
Provided are a nanoparticle-polymer fluorescent composite and a method of preparing the same. The method includes preparing magnetite (Fe3O4) nanoparticles, mixing the magnetite (Fe3O4) nanoparticles, an organic polymer having an aliphatic carbon chain, and a solvent for dissolving the organic polymer to prepare a preliminary composite and drying the preliminary composite to form a nanoparticle polymer composite, and irradiating a pulse laser to the nanoparticle polymer composite to change the magnetite (Fe3O4) nanoparticles to Wustite nanoparticles and providing conjugated polymer characteristics to the organic polymer.
