Title:
III-V SEMICONDUCTOR/SiO2 NANOPARTICLE AND AGENT FOR LABELING BIOLOGICAL SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2007/138851
Kind Code:
A1
Abstract:
Disclosed is a luminescent material using less-toxic III-V semiconductor nanoparticles and having high luminous intensity. This luminescent material hardly deteriorates. Also disclosed is an agent of labeling biological substances, which uses the III-V semiconductor nanoparticles. Specifically disclosed is a III-V semiconductor/SiO2 nanoparticle which is characterized by having a core made of a III-V semiconductor and having a particle diameter within the range of 1-50 nm, and a shell made of SiO2.
