| This work focuses on the design of new methods for synthesis of ternary alloy quantum dots of Cdx ZnySez. These quantum dots can capture a wide range of the solar spectrum and are to be used in the manufacturing of solar cells. We have designed a one-pot fast synthesis of ternary quantum dots with photoluminescence ranging from the red through to the blue region of the spectrum. The photoluminescence peaks indicate absorption over a narrow range (30 nm) of the spectrum for quantum dots of a given type. We have also studied the effect of solvent boiling point and the type of solvent on the synthesis and on the photoluminescence properties of these quantum dots. The type of solvent plays an important role in the photoluminescence properties of quantum dots. High boiling point non-polar solvents shift the photoluminescence peak to higher wavelength and low boiling point polar solvents shift the photoluminescence peak to lower wavelength. |
