    摘要: A low-temperature process for creating a semiconductive device by printing a liquid composition containing semiconducting nanoparticles. The semiconductive device is formed on a polymeric substrate by printing a composition that contains nanoparticles of inorganic semiconductor suspended in a carrier, using a graphic arts printing method. The printed deposit is then heated to remove substantially all of the carrier from the printed deposit. The low-temperature process does not heat the substrate or the printed deposit above 300° C. The mobility of the resulting semiconductive device is between about 10 cm2/Vs and 200 cm2/Vs.

    摘要: A method and apparatus is provided for activating a layer (208, 308, 408) of free standing quantum dots. The apparatus comprises a first coil (216, 316, 426) disposed contiguous to a light emitting device (200, 300, 400, 612) including the free standing quantum dots. An alternating current is supplied to the coil (216, 316, 426) for generating an electric field, and the plurality of free standing quantum dots are subjected to the electric field thereby causing photons to be emitted therefrom. A structure (214, 328), such as a housing (620) of a portable electronic device (610, 710) may be positioned either, when opaque, between the light emitting device (300, 400) and the coil (316, 426), or, when transparent, on a side of the light emitting device (200) opposed to the coil (216).

    摘要: An apparatus is provided for modulating the photon output of a plurality of free standing quantum dots. The apparatus comprises a first electron injection layer (210, 310, 410) disposed between a first electrode (212, 312, 412) and a layer (208, 308, 408) of the plurality of free standing quantum dots. A hole transport layer (206, 306, 406) is disposed between the layer (208, 308, 408) of the plurality of quantum dots and a second electrode (204, 304, 404). A light source (224, 324, 424) is disposed so as to apply light to the layer (208, 308, 408) of the plurality of free standing quantum dots. The photon output of the layer (208, 308, 408) of the plurality of free standing quantum dots is modulated by applying a voltage to the first and second electrodes (212, 312, 412, 204, 304, 404). Electrons excited to a higher energy state within layer (208, 308, 408) of the free standing quantum dots by the light source (224, 324, 424) are prevented from returning to a lower state by electrons from the electric field of the applied voltage, and therefore the free standing quantum dots are prevented from emitting a photon. The voltage source (216, 316, 416) may be modulated to vary the photon output.
