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

摘要

THIS INVENTION RELATES AN OPTOELECTRONIC MATERIAL (13) COMPRISING A UNIFORM MEDIUM (15) WITH A CONTROLLABLE ELECTRIC CHARACTERISTIC; AND SEMICONDUCTOR ULTRAFINE PARTICLES (14) DISPERSED IN THE MEDIUM AND HAVING A MEAN PARTICLE SIZE OF 100 NM OR LESS, AND AN APPLICATION DEVICE USING THE SAME.THIS INVENTION ALSO RELATES TO A METHOD OF MANUFACTURING AN OPTOELECTRONIC MATERIAL BY IRRADIATING A LASER BEAM ONTO A FIRST TARGET OF (2506) A SEMICONDUCTOR MATERIAL, PLACED IN A REACTION CHAMBER IN LOW PRESSURE RARE GAS AMBIENT, AND A SECOND TARGET (2513) OF A MEDIUM MATERIAL WITH A CONTROLLABLE ELECTRIC CHARACTERISTIC, PLACED IN THE REACTION CHAMBER, CONDENSING/GROWING A SEMICONDUCTOR MATERIAL ABLATED FROM THE FIRST TARGET TO BE COLLECTED AS ULTRAFINE PARTICLES HAVING A MEAN PARTICLE SIZE OF 100 NM OR SMALLER ON A SUBSTRATE (2516) PLACED IN THE REACTION CHAMBER, AND CONDENSING/GROWING A MEDIUM MATERIAL ABLATED FROM THE SECOND TARGET TO BE COLLECTED ON THE SUBSTRATE PLACED IN THE REACTION CHAMBER, THUS FORMING AN ULTRAFINE-PARTICLES DISPERSED LAYER HAVING SEMICONDUCTOR ULTRAFINE PARTICLES DISPERSED IN THE MEDIUM ON THE SUBSTRATE.(FIG 1A,1B,1C)
