▲ [19p-231B-4] [INVITED] Nanomaterials synthesized in a microfactory and enhanced performances of optoelectrical devices
キーワード：laser ablation, quantum dot, nanoparticle
Recently, it has been widely recognized, from various experimental and theoretical researches, that pulsed laser irradiation in a liquid generates high temperature and pressure at around a target surface, which we treat a microfactory for nanomaterial synthesis. In this talk, the author will introduce recent research progresses for nanomaterial synthesis by PLA in the microfactory, exposed at high temperature and pressure during synthesis. As another topic, the author will introduce colloidal quantum dots (QDs) or colloidal nanoparticles (NPs) synthesized by PLA, whose nanomaterials can be integrated to develop an optoelectrical device via a solution process. Especially, the author will present a silicon (Si) QD light-emitting diode (QD-LED) in a blue wavelength region and flexible material for Si-NP/polymer hybrid film.
