Abstract
The present invention relates to a composition including quantum dots and an emission stabilizer, products including same, and methods, including methods for improving, or enhancing the emission stability of quantum dots. Inclusion of an emission stabilizer in a composition can improve or enhance the stability of at least one emissive property of the quantum dots in the composition against degradation compared to a composition that is the same in all respects except that it does not include the emission stabilizer. Examples of such emissive properties include, by way of example only, lumen output, lumen stability, color point (e.g., CIE x, CIE y) stability, wavelength stability, FWHM of the major peak emission, absorption, solid state EQE, and quantum dot emission efficiency.
