In　the　present　work,　we　investigated　the　crystal　structure,　electronic　structure,　optical　properties　and　electrical　properties　of　the　wurtzite　type　ZnO　oxide　at　exoteric　pressures　of　500　GPa　based　on　the　density　functional　theory　ab-initio　calculations　framework.　The　results　show　that　the　lattice　of　ZnO　is　decreased　at　500　GPa　and,　at　the　same　time,　the　Zn-O　bond　length　and　the　O-Zn-O　bond　angle　are　decreased　while,　however,　the　compressibility　varies　in　different　crystal　directions　and　the　symmetry　remains　the　same.　The　band　gap　is　direct　at　500　GPa　with　the　band　gap　value　rising　to　1.65　eV.　The　number　of　the　energy　bands　decreases　and　so　does　the　density　of　states.　An　obvious　localization　effect　of　the　electrons　is　observed　at　500　GPa.　The　absorption　peaks　move　towards　the　high　energy　region,　and　the　absorption　decreases　for　low　energy　photon　and　increases　for　the　high　energy　photon.　The　results　from　our　analysis　show　that　the　density,　effective　mass　and　the　mobility　of　the　carriers　near　Fermi　level　decrease　under　500　GPa,　leading　to　a　reduced　performance　of　their　electrical　properties.　©　2016,　Chinese　Journal　of　High　Pressure　Physics.　All　right　reserved.
