Description
  • GH4 se nechá hořet ve vzduchu do vytvoření prášku, který se částečně rozpouští ve formě malých koloidních částic v acetonu nebo cyklohexanové směsi Částice se skládají ze 73% germania a 27% kyslíku Leptáním kyselinou fluorovodíkovou získají částice modrou či modrozelenou luminiscenci. Modře svítící částice obsahují nepatrné množství kyslíku a silně se hromadí Luminiscence se vysvětluje velikostí kvantování hodnot energie elektronu. se pohybují v elektrickém poli k anodě aby utvořily velmi tenkou vrstvu, která po přepnutí na polarizaci katodou vytvoří červenou fotoluminiscenci s dobou života několika nanosekund. Tato fotoluminiscence za přítomnosti elektronů je řízena? potenciálem elektrody. (cs)
  • GH4 is burnt in air to yield a powder which partly dissolves in the form of small colloidal particles in an acetone/cyclohexane mixure. The particles consist of 73% germanium and 27% oxygen. Upon etching with hydrofluoric acid, he particles acquire a blue or blue-green luminescence. The blue-luminescent particles contain no noticeable amount of oxygen and are strongly agglomerated. The luminescent id explained by size quantization of the electronic energy levels. The particles move in an electric field to the anode to form a very thin layer, which, after switching to cathodic polarization, develops a red photo-luminescence, which has a life time of a few ns. This electro-assisted photo-luminescence is gated by the potential of electrode.
