ZnS nanostructures were grown on Si substrates in high vacuum by modified thermal evaporation technique. Morphology, chemical composition and structural properties of grown ZnS nanostructures were studied using scanning electron microscope (SEM), X-ray diffractometer and transmission electron microscope (TEM). SEM studies showed that morphology of the grown structures varies with incident flux and source temperature. TEM studies showed that grown nanostructures are single crystalline in nature without structural defects such as stacking faults and twins. No catalytic particle was included in this growth process, and hence these micro and nanostructures were assumed to grow by VS mechanism.

Developing heavy-metal-free materials with wide tunable emission is important to light-emitters. The alloying method is utilized in ZnSe magic size clusters (MSCs) with Te to form ZnSeTe and manipulate the band gap structure in ZnSe. The growth of ZnTe on alloyed ZnSeTe quantum dots (QDs) forms ZnSeTe/ZnTe core/shell nanostructures, showing the tunable photoluminescence emission peak from 450 to 760 nm with the different thicknesses of ZnTe shell.

The optimal method for three-dimensional thermal imaging within cells involves collecting intracellular temperature responses while simultaneously obtaining corresponding 3D positional information. Current temperature measurement techniques based on the photothermal properties of quantum dots face several limitations, including high cytotoxicity and low fluorescence quantum yields. These issues affect the normal metabolic processes of tumor cells.
