Wide visible and unique NIR fluorescence from SiC nanocrystals embedded in carbon rich SiC matrix derived from liquid polycarbosilane
Abstract
A novel epitaxial growth of SiC nanocrystals embedded in carbon rich amorphous SiC films deposited using liquid polycarbosilane as precursor. These films exhibit wide visible and unconventional NIR fluorescence with exceptionally short lifetimes of 146 ps and 138 ps. Fabrication of LEDs is a potential application of these materials.
