The emission wavelengths of CdTe nanocrystals could be tuned by the refluxing time. Bioinorganic conjugates between CdTe nanocrystals and BSA were formed via electrostatic/coordinate self-assembly. The photoluminescence intensity of the bioinorganic conjugates was improved obviously. BSA could stabilize the CdTe nanocrystals, and the bioinorganic conjugates at room temperature were stable for a long time. We also demonstrated that CdTe nanocrystals could be blocked with BSA and avoid the nonspecific adsorption.展开更多

The luminescent intensity and the solubility of surfactants encapsulated with CdTe nanocrystals can be tailored by choosing the surfactants with different hydrocarbon chain lengths. The ability to encapsulate different color emission nanocrystals with polymerizable surfactants gives great promise for the fabrication of transparent bulk nanocrystal-polymer hybrids.展开更多
