QD Size from Optical Absorption and Luminescence Spectra

QD Size from Optical Absorption and Luminescence Spectra 

CdSe NPs are one typical kind of quantum dots, which can be synthesized by colloidal chemistry methods and can be doped into sol-gel materials. Optical absorbance measurements of colloidal solutions were performed using a spectrophotometer with a resolution of 1.0 nm. The PL spectra were collected with a spectrofluorophotometer with a resolution of 1.0 nm, under excitation at 390 nm [67].
