synthesis and oxidation of luminescent silicon nanocrystals from silicon tetrachloride by very high frequency nonthermal plasma

R Gresback, T Nozaki, K Okazaki - Nanotechnology, 2011 - iopscience.iop.org

... Photoluminescence (PL) measurements were performed on samples prepared by direct deposition
of NCs onto glass substrates and a circular 405 nm diode laser (World Star Tech, TECBL- 30GC-405) was
used as the excitation source, while a CCD (Pixis, 100BR-32) and ...
