Abstract:
PURPOSE: An optoelectronic material and a method for manufacturing an optoelectronic material is provided to obtain an optoelectronic material which emits at a constant illumination level without being oxidized in air. CONSTITUTION: A target material(107) is arranged in a reaction chamber(101). An accumulation substrate(109) is arranged inside of the reaction chamber. A laser light is irradiated on the target material in order to cause an ejection of the target material. Microparticles resulted from condensing the ejected material in air atmosphere are collected on the accumulating substrate in order to obtain an optoelectric material. In an ablation operation where the target material is ejected by illuminating the laser light, a nitride atmosphere gas is introduced at a constant pressure, and at least a surface of a whole portion of the microparticles is nitride-treated.
Abstract:
The present invention is to fabricate a quantum dot functional structure having ultra-fine particles homogeneously distributed in a transparent medium by efficiently fabricating high-purity ultra-fine particles having a single particle diameter and uniform structure and depositing the ultra-fine particles onto a substrate in conjunction with the transparent medium. For these purposes, an apparatus for fabricating a quantum dot functional structure is provided. The apparatus comprises: an ultra-fine particle generating chamber for generating high-purity ultra-fine particles by exciting a semiconductor target with pulsed laser light in a low-pressure rare gas atmosphere, and then by allowing the semiconductor target to be detached or ejected by ablation reaction and condensed and grown in the gas; an ultra-fine particle classifying chamber for classifying the ultra-fine particles; a depositing chamber for depositing the high-purity semiconductor ultra-fine particles and the transparent medium by exciting a transparent medium target with excimer laser light at the same time or alternately when the high-purity semiconductor ultra-fine particles are collected onto the substrate, and by collecting the substance generated through ablation reaction onto the substrate; and a carrier gas exhaust system.
