1. A treated quantum dot (QD) with suppressed photobrightening comprising:

  • a QD nanocrystal having a surface with a maximum cross-sectional dimension of 10 nanometers (nm), capable of emissions in the visible spectrum of light;

    elements attached to the surface of the QD nanocrystal consisting of cations; and

    ,wherein the treated QD emits a non-varying intensity of first wavelength of light in the visible spectrum when subjected to a continuous exposure of a second wavelength of light having an intensity of greater than 50 watts per square centimeter (W/cm2).
