Are the effects of surface defects on spectroscopic properties (absorption/ emission of a nano particle) been properly characterized before?
Some nanoparticles show clear surface emission (e.g. CdS), which has been characterized reasonably well.
well, I meant nanocrystals. Here is an example of nanocrystals ( although not really nice ones). http://onlinelibrary.wiley.com/doi/10.1002/crat.201300185/abstract
really you find a lot of if you just google " CdS surface emission" or any other material you are interested in.
Christian, I meant actually di-electric crystals, like rare earth doped laser crystals- Nd:YAG and so on. They should be different from surface emission shown from a quantum dot of CdSe, I guess ?
But thanks for the insights, you are really helping me here !!
well you should have made that clear from the start ;), or did I miss something?Anyways, in this field I have very limited knowledge. Still I guess one can assume that even for rare-earth nanoparticles defects scatter phonons. Therefore it probably does matter! Good Luck!
Sorry about that Christian, but thank you very much for your insights, they should definitely prove to be helpfull !!
