The Size-Dependence of 1,5-Diphenyl-3-naphthyl-2-pyrazoline Nanocrystals

1,5-Diphenyl-3-naphthyl-2-pyrazoline nanocrystals with different sizes from 400 to 20 nm were prepared by the reprecipitation method. As the nanocrystal size decreased, the nanocrystal absorption peak was observed to shift to high-energy side due to size effect, and in the same period the peak shape...

Beschreibung
Zusammenfassung:	1,5-Diphenyl-3-naphthyl-2-pyrazoline nanocrystals with different sizes from 400 to 20 nm were prepared by the reprecipitation method. As the nanocrystal size decreased, the nanocrystal absorption peak was observed to shift to high-energy side due to size effect, and in the same period the peak shape changed from asymmetric to symmetric due to the gradual disappearance of the aggregate absorption.
