Surface plasmon enhanced blue–green photoluminescence from carbon-rich amorphous silicon carbide films

Giant photoluminescence enhancement in SiC nanocrystals by resonant semiconductor exciton–metal surface plasmon coupling

“…It is thus necessary to improve the fluorescence intensity of the SiC NCs for their practical application. Plasmon-enhanced PL has recently been observed in nanocrystalline SiC films fabricated using the chemical etching method [25,26]. Ag-nanoparticles-induced PL enhancement has been observed in SiC NCs with a spacing layer of the polyelectrolytes film tens of nanometers in thickness [27].…”

Amorphous carbon-based films with surface-plasmon-enhanced full-color photoluminescence

“…In the past two decades, SPs have been extensively studied to enhance the luminescence efficiency of light emitting materials and devices, such as InGaN/GaN [3,6,9,10], silicon quantum dots (Si-QD) [5] and ZnO films [11][12][13][14][15][16], for the applications of ultrabright light-emitting diodes (LEDs), or ultraviolet UV lasers. In our previous studies, SPs were successfully used to enhance the light emission from a-Si 1 − x C x :H films (emitting blue-green light at 480 nm) [17] and a-C:H films (emitting blue light at 445 nm) [18]. However, these enhancement studies were only carried out with a limited emission range.…”
