Core/shell type semiconductor nano- particle and the production method

摘要

This invention, being the core/shell type semiconductor nano- particle, has sufficient luminous strength, offers the core/shell type semiconductor nano- particle which at the same time does not have blinking phenomenon (blinking). The core of this invention/the shell type semiconductor nano- particle being the core/shell type semiconductor nano- particle where mean diameter is 2 - 50nm, has center between the core section and the shell, band gap width of bulk crystal of the constitution which at the same time is identical with the constitution of each one of the particular core section, the shell and center, the core section the shell features that it is large to the order of center.
