| Abstract: | HgS acicular nanocrystals conjugated with gelatin were successfully synthesized in aqueous solution of gelatin at room temperature. SEM images showed that when the reaction time reached 2 d, the particles of HgS was formed while the reaction time reached 15 d, the particles turned into the acicular nanoparticles. The average diameter of the acicular nanoparticles was 87 nm with the length of 1.3 μm. The quantum-confined effect of the HgS nanoparticles was confirmed by the ultraviolet-visible and fluorescence spectrum. The results indicate that the change of gelatin conformation not only induce the nucleation, but is favorable to the pattern change of HgS nanoparticles. |
