Synthesis of White Light Emitting Water-soluble CdZnS Quantum Dots at Room Temperature
Abstract: Water-soluble alloyed CdZnS quantum dots (QDs) have been successfully prepared at room temperatures by reacting a mixture of Cd(CH3COO)2 and Zn(CH3COO)2 with Na2S using thiolactic acid (TLA) as a surface capping agent. The photoluminescence (PL) spectra of the alloyed QDs are determined on the basis of the Cd2+/Zn2+ molar ratio, reaction pH, intrinsic Cd2+and Zn2+reactivities toward Na2S and the concentration of capping agent. A systematic blue shift in emission wavelength …

Nano Ultraviolet Finishing of Textiles Using Inorganic UV- Blockers–The Sustainable Approach of Producing Protective Clothing for Better Tomorrow
Abstract: The diminution of the ozone stratum,due to global warming, is likely to intensify existing health effects caused by exposure to ultraviolet (UV) radiations, as stratospheric ozone is a predominantly effective UV radiation absorber. As the ozone layer becomes thinner, the protective filter provided by the atmosphere is gradually abridged. Subsequently, human beings and the environment are exposed to higher UV radiation levels, particularly higher UV-B levels, which have the greatest …
