LIGHT EMISSION SILICON PARTICLE AND MANUFACTURING METHOD OF LIGHT EMISSION SILICON PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a light emission silicon particle and a manufacturing method of the light emission silicon particle, the light emission silicon particle having silicon on its surface terminated with carbon, capable of providing a desired luminous color in a wide range from visible to near infrared and emitting light with high efficiency.SOLUTION: There are provided a light emission silicon particle and a manufacturing method of the light emission silicon particle including a porous silicon forming process for forming porous silicon by chemical etching a silicon raw material by using a solution containing hydrofluoric acid and oxidant and an organic group terminated silicon particle forming process for immersing the resulting porous silicon in an organic solvent, radiating an ultraviolet pulse laser with a wavelength of 323 nm or less while stirring the organic solvent to obtain silicon particles having a surface terminated by a monovalent organic group containing a carbon atom.SELECTED DRAWING: None
