TECHNOLOGY FOR SYNTHESIS OF NANO-LUMINESCENT MATERIAL USING MICROORGANISM

摘要

PPROBLEM TO BE SOLVED: To provide a recycling or materializing technology to convert selenic acid, selenious acid, telluric acid and tellurous acid and heavy metals such as cadmium in a waste to a nano-luminescent material such as cadmium tellurate by using the metabolic action of microorganisms. PSOLUTION: A group II-VI semiconductor nano-crystalline luminescent material such as cadmium selenide is synthesized by culturing a microorganism capable of metabolizing and reducing oxide anion of a metal-like element classified in oxygen group such as selenic acid and tellurous acid in the presence of a heavy metal cation such as cadmium or using the bioactivity of the microorganism.
