The structural stability of both capped and uncapped CdS nanocrystals against thermal energy have been investigated by high-resolution powder x-ray diffraction. The x-ray diffraction measurements reveal that the wurtzite crystal structure of uncapped CdS nanocrystals is extremely unstable and undergoes phase transformation towards zinc-blende phase even at room temperature with time. However, the thiol-capped CdS nanoparticles are found to be structurally stable at room temperature and the role of capping agent, which provides structural stability to CdS nanoparticles has been investigated.
