Synthesis and properties of single luminescent silicon quantum dots
... luminescence from porous Si in 1990 raised hopes it may find a new lease of life in the emerging field of optoelectronics. First, the luminescence was shown to be emitted from nanostructures in a porous Si network. Later the same emission was seen from Si nanocrystals and the concept of a Si quantum ...
