Formation of silicon nanocrystals in sapphire by ion implantation and the origin of visible photoluminescence
(Amer Inst Physics, 2006)
Silicon nanocrystals, average sizes ranging between 3 and 7 nm, were formed in sapphire matrix by ion implantation and subsequent annealing. Evolution of the nanocrystals was detected by Raman spectroscopy and x-ray ...
Cytotoxic effects of lead and mercury ions on root tip cells of Cicer arietinum L
(Parlar Scientific Publications (P S P), 2009)
In the present study, the cytotoxic effects of different concentrations of lead (Pb) and mercury (Hg) ions on Cicer arietinum L. root tip cells were investigated. For this aim, we used the aermination percentage, root ...
