Abstract:
Cuboid-shaped CdS particles were synthesized with sol-gel method by using thiourea as surface modifier and characterized by X-ray diffraction, transmission electron microscopy, infrared absorption spectrum and fluorescence spectrum. The results show that the sulfur atoms in thiourea molecules coordinate with Cd2+ ions on the surface of the nanocrystals. The thiourea-modified CdS particles have a zinc blende crystal structure and good fluorescent characteristics. The cuboid-shaped CdS particles are probably assembled by hydrogen bonding between primary CdS nanocrystals surface-capped with thiourea. The result will promote the researches into molecular self-assembly of nanocrystals and help develop novel luminescence material.
