METHOD AND APPARATUS FOR PRODUCING SEMICONDUCTIVE ULTRAFINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing semiconductive ultrafine particles having a narrow particle size distribution and excellent light absorption and emission properties, in good productivity. SOLUTION: In the method, the first substance containing a positive element and the second substance containing a negative element are used as a raw material for the semiconductor, a reverse micell liquid in which the aqueous solution of the first substance or the second substance is dispersed in an organic liquid phase medium is contacted with another raw material for the semiconductor in a tubular passage rector to make compound semiconductor crystals grow in the medium, and the Reynolds number of a reaction liquid phase when both raw materials are brought into contact is at least 1.
