OPTOELECTRONIC MATERIAL, DEVICE USING THE SAME AND METHOD FOR MANUFACTURING OPTOELECTRONIC MATERIAL

摘要

This invention relates an op toelectronicmaterial comprising a uniform medium with acontrollable electric characteristic; and semiconductorultrafine particles dispersed in the medium and having amean particle size of 100 nm or less, and an applicationdevice using the same. This invention also relates to amethod of manufacturing an optoelectronic material byirradiating a laser beam onto a first target of asemiconductor material, placed in a reaction chamber inlow pressure rare gas ambient, and a second target of amedium material with a controllable electriccharacteristic, placed in the reaction chamber,condensing/growing a semiconductor material ablatedfrom the first target to be collected as ultrafine particleshaving a mean particle size of 100 nm or smaller on asubstrate placed in the reaction chamber, andcondensing/growing a medium material ablated from thesecond target to be collected on the substrate placed inthe reaction chamber, thus forming an ultrafine-particlesdispersed layer having semiconductor ultrafine particlesdispersed in the medium on the substrate.
