Scope

This Standard specifies the UV-Vis absorption spectroscopy for the characterization of
cadmium selenide (CdSe) quantum dot nanocrystals.
This Standard is applicable to the dispersion liquid of cadmium selenide quantum dot
nanocrystals coated with surfactant molecule---TOPO, Trioctylphosphine formed in n-hexane.
The UV-Vis absorption spectrum characterization of dispersion liquids of cadmium selenide
quantum dot nanocrystals coated with other surfactant molecules formed in various non-polar
reagents, cadmium selenide quantum dot nanocrystals synthesized in aqueous systems and
semiconductor quantum dot nanocrystals of other compositions may also take this Standard as
a reference.

Summary	This standard specifies the cadmium selenide (CdSe) quantum dot nanocrystals UV-visible absorption spectroscopy characterization methods. This standard applies to the surfactant molecules-dispersion octyl phosphine oxide is three (TOPO, Trioctylphosphine) coated CdSe quantum dot nanocrystals formed in n-hexane. Dispersions other surfactant molecules coated CdSe quantum dot nanocrystals in a variety of non-polar reagent formed, synthesized in aqueous systems blessing selenide quantum dots and other semiconductor nanocrystal quantum dots composed of nano- crystal UV-visible absorption spectroscopy to characterize it may refer to this standard.
