Luminescent small-diameter 3C-SiC nanocrystals …
2007/8/10· Experiments found that the suspensions of Si nanocrystals exhibit tunable violet–blue photoluminescence (PL) because of the quantum confinement on small diameter silicon nanocrystals [2, 5]. Based on the importance in blue emission, much work has recently been directed toward the realization of stable and strong blue/violet emission [ 6–10 ], which is difficult to achieve from PS.
