Abstract	Quantum dots (QD) are nanoparticles specially semiconductors with the photoluminescence (PL) property with a variable wavelength. These ranges from the scale of 1-6 nm that can subsist in a liquid or a solution with a constancy state. This photoluminescence or fluorescence is produced due to their surface defects caused on the surface of the QD which results in the absorbance of light from sources of different wavelength. Those tuneable wavelengths of the photoluminescence can be influenced by their shape, size and structure of the QD. The transitional optical properties of QD helps in generating sensors in the field of instrumental analytical chemistry, biosensors to mutual interaction with analytes. These QD can be manufactured through possible colloidal synthesis similar to handed down chemical processes and electrical gating. The high extinction coefficient and incredibly quick optical nonlinearities contributes a high influence in optical properties of QD. More over the QD produced with high efficiency and stability is used for the research purposes which in turn provides a quite narrow emission spectrum, where the size of is directionally proportional to wavelength. The high compatibility, adjustable PL and increased photo stability prioritise the advantage of chemical analysis.
