Catalytic synthesis and photoluminescence of needle-shaped 3C–SiC nanowires

Synthesis and photoluminescence of needle-shaped 3C–SiC nanowires on the substrate of PAN carbon fiber

“…Gundiah et al [11] reported that the photoluminescence peak of SiC nanowires by heating a gel containing activated carbon and silica was located at the wavelength of 400 nm. Feng et al [12] measured the room temperature photoluminescence spectrum of the needle-shaped SiC nanowires prepared from SiC powders in a thermal evaporation process with iron as catalyst.…”

Large-scale synthesis and photoluminescence properties of hexagonal-shaped SiC nanowires

“…6). Two strong ultraviolet light emission peaks are observed at wavelength of 289 and 391 nm, which show significant blueshifts compared with the previous reports [2,[4][5][6][7]. The emergence of peak at 289 nm with a large blueshift is due to the existence of oxygen defects in amorphous layer and the special rough core-shell interface [6,7].…”

“…SiC nanorods were reported have a PL peak at about 340 nm [4]. SiC nanowires and needleshaped SiC nanowires show their PL peaks at 400 and 450 nm, respectively [2,5]. SiC nanocables possess two broad emission peaks at 340 and 440 nm [6].…”

“…On the other hand, an important field of these applications is in microelectronics and optoelectronics in the foreseeable future [1] because of intensive light emission from indirect-gap semiconductors [2,3]. Although the research on the synthesis of SiC nanowires have extended over 10 years, several literatures on photoluminescence (PL) performances of SiC nanowires are reported so far [1,2]. And these authors present some extraordinary different results on SiC nanowires' PL properties, which are listed as follows.…”

Influence of raw powder size, reaction temperature, and soaking time on synthesis of SiC/SiO2 coaxial nanowires via thermal evaporation

“…The nanowire will enhance the interfacial bonding strength of rubber and reinforcement. 15) In addition, coaxial SiC/ SiOx nanowires may be used as a good light emitting material since it can emit stable and strong intense blue-green 16) or violetblue 17) light. Therefore, synthesis and properties of SiC/SiO2 core-shell nanowires, including the effect of reaction conditions, should be attractive research fields.…”
