In zno, zn2+ ions occupy the interstitial sites and electrons are trapped in the interstitial sites for the neutralization. Crystals that shows such type of defects are generally colored. Zinc oxide is White in color but on heating it turns into yellow because on heating is losses oxygen reversibly at high temperature.
