    摘要: A process is disclosed for preparing water soluble particles of a luminescent material which is a rare earth material, a doped compound semi-conductor or a doped inorganic compound which comprises coating particles of said luminescent material, either during production of the particles, or subsequently, with an organic acid or Lewis base such that the surface of the coating possesses one or more reactive groups.

    摘要: The light emitter is fabricated from a silicon substrate (2) that has a layer of porous silicon (3) on its upper surface. A hole transporter (4) is applied to the upper surface of the porous silicon (2) and penetrates the channels (3′) formed within the porous silicon. An upper semitransparent p-type material such as NiO is used as the upper contact (5) to the hole transporter and a further contact is formed on the base of the silicon wafer (2). The penetration of the hole transporter into the interstices between the silicon particles significantly improves the efficiency of the light emitter by up to two orders of magnitude. The light emitter is particularly suited to use in VLSI and display applications.
