The photoluminescence properties of the porous Si films nanostructured by CdS particles (d = 3.0nm) have been investigated. It is shown that the deposition of CdS nanoparticles on the surface of porous Si leads to a shift of the photoluminescence spectrum of the nanoparticles, covered with superficially active agent, in short-wave area. It is established that a violation of the integrity of the shell of CdS nanoparticles from superficially active agent leads to the formation of at least two fractions of nanoparticles with different sizes. Well resolved bands of a photoluminescence with maximums of 480 and 530 nanometers. correspond to these fractions.
Keywords: nanoparticles, porous Si, photoluminescence.

You have noted very interesting points! ps nice internet site.Blog monetyze
Wow! Thank you! I continually wanted to write on my blog something like that. Can I take a fragment of your post to my blog?
Hey there! Do you know if they make any plugins to help with Search Engine Optimization? I’m trying to get my blog to rank for some targeted keywords but I’m not seeing very good results.
If you know of any please share. Appreciate it!
