Silicon nanocrystals (SiNCs) have great potential to become environmental friendly alternatives to heavy-metal containing nanocrystals for applications including medical imaging
lighting and displays. SiNCs exhibit excellent photostability
non-toxicity and abundant resources
but their often reported inefficient and spectrally limited light emission seriously impair their applications. Here we demonstrate a new method that converts SiNCs into an efficient and robust multi-chromatic phosphor. Using ~15 keV electron-beam irradiation of oxide-capped SiNCs
we introduce several types of color centers into the nanocrystal's oxide shell with efficient blue
green and red emission bands
together yielding warm-white photoluminescence
even for a single SiNC. Introduced centers are not native to the original system and we relate them to known defects in silica. Unlike in the silica host
however
here the centers are efficiently optically excitable. Provided further optimization and up-scaling of this method
e-beam irradiated SiNCs can be of great interest as white phosphors for applications such as LEDs.
