NiO nano-crystal powders with cubic structure were synthesized by molten salt method. The synthesized materials were characterized by XRD, TEM, N2 adsorption-desorption and TG, etc. Not only are the eminent characters...
Perylene nanocrystals with different sizes(10-250 nm) were prepared by reprecipitation. Compared with the absorption spectrum of perylene acetone solution, a new J aggregate absorption peak appeared in the absorption ...
