Core/shell type nano- particle, vital physical sign medicine and production method of particle

摘要

This invention had with the core which was formed with Ge and the shell where it was formed with inorganics, being the core/shell type nano- particle which features that mean diameter of the aforementioned core is the range 1 - 50nm, organism virulence and load to environment were little, it was superior in chemical stability, the case where relative luminous strength was high, in addition continued optical lighting it can offer the semiconductor nano- particle whose decrease of luminous strength is small.
