Abstract: PROBLEM TO BE SOLVED: To provide a fine particle structure body for preventing aggregation, a light-emitting device using it, and a method for manufacturing the fine particle structure body. SOLUTION: A fine particle structure body is provided with a plurality of fine particles 11, made of ZnO or the like, and each of the fine particles 11 is connected to one another in a network form by a crosslinking part 12. More specifically, the crosslinking part 12 that exists among particles becomes a support part, thus preventing the fine particles 11 from being aggregated. Each of the fine particles 11 is composed of a fine crystal with a crystal particle diameter of 100 nm or less and has an inter-band luminous function and a donor acceptor pair luminous function. This sort of fine particle structure body is used as a material for composing the luminous part of a light-emitting device. The fine particle structure body is manufactured by applying a voltage between positive and negative electrodes with pure water as an electrolyte, a highly pure Zn plate as the positive electrode, and a semiconductor substrate as the negative electrode.

Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable semiconductor light emitting element having excellent characteristics and a long service life, a method for manufactur ing the element, and an optical recording and/or reproducing device using the light element as a light emitting element. SOLUTION: In a semiconductor light emitting element using a II-VI compound semiconductor, at least an active layer 7 is formed to have rugged surfaces and p-type contact layers 11, 12, and 13 are formed to have flat surfaces. The standard deviation of the height of the rugged surfaces of the active layer 7 is adjusted to, for example, about 1-3nm. In addition, the ratio of the intensity of a molecular beam of a group VI element to that of a molecular beam of a group II element is optimized by changing the ratio in accordance with a layer to be grown when clad layers 5 and 9, light guide layers 6 and 8, the active layer 7, the contact layers 11, 12, and 13, etc., are grown manufacturing the semiconductor light emitting element.
