text: Organic semiconductors always show very small overlap between the absorption and photoluminescence spectra, so they show weak absorption to light emitted from the same material, while colloidal quantum dot LEDs are always based on very thin quantum dot film due to the very low carrier transport property, so their light absorption is very weak.
