    Abstract: Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (“3D”) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy.

  • Publication number: 20130050685
    Abstract: A composite structure having an embedded sensing system is provided, along with corresponding systems and methods for monitoring the health of a composite structure. The composite structure includes composite material and an optical fiber disposed within the composite material. The optical fiber includes a plurality of quantum dots for enhancing its non-linear optical properties. The quantum dots may be disposed in the core, in the cladding and/or on the surface of the optical fiber. The optical fiber is configured to support propagation of the signals and to be sensitive to a defect within the composite material. The quantum dots create a non-linear effect, such as a second order effect, in response to the defect in the composite material. Based upon the detection and analysis of the signals including the non-linear effect created by the quantum dots, a defect within the composite material may be detected.

  • Publication number: 20130047503
    Abstract: An illumination device with a semiconductor light emission solution has a wavelength up conversion feature and is suited for plant cultivation in a greenhouse environment. The best mode is considered to be a light device with at least one blue LED (101) with wavelength up conversion binary alloy quantum dots (110, 120, 130, 140, 150, 160) made by colloidal methods that are arranged to produce an emission spectrum similar to photosynthetically active radiation (PAR) spectrum with the blue LEDs. The methods and arrangements allow more precise spectral tuning of the emission spectrum for lights used in plant cultivation. Therefore unexpected improvements in the photomorphogenetic control of plant growth, and further improvements in plant (310, 311) production are realized. The device is especially advantageous for greenhouses that already have legacy LED systems. These LED systems can often just be upgraded by adding the quantum dot array to arrive at the lighting solution.

  • Publication number: 20130042906
    Abstract: A quantum dot sensitized solar cell including an anode, a cathode and an electrolyte is provided. The anode includes a semiconductor electrode adsorbed with a plurality of quantum dots. The quantum dots have a broad light absorption range that covers the ultraviolet, visible and infrared regions. The broad absorption range increases the ability of light harvesting, and accordingly, leads to an improved conversion efficiency of the solar cell.

  • Publication number: 20130044457
    Abstract: The invention relates to a lighting apparatus comprising a conversion material (2) for converting primary light (4) into secondary light (5), wherein the conversion material (2) comprises converting photolummescent material (15), which degrades to non-converting photolummescent material over time when the conversion material (2) is illuminated by the primary light (4). The conversion material (2) is adapted such that, when the conversion material (2) is illuminated by the primary light (4), the relative decrease in concentration of the converting photolummescent material (15) within the conversion material (2) is larger than the relative decrease in intensity of the secondary light (5). This allows the lighting apparatus to provide an only slightly reduced absorbance of the primary light, even if a large part of the photolummescent material has been bleached, and thus a longer lifetime, with the same or a slightly reduced intensity of the secondary light.

  • Publication number: 20130045499
    Abstract: A ligand design allows compact nanoparticle materials, such as quantum dots (QDs), with excellent colloidal stability over a wide range of pH and under high salt concentrations. Self-assembled biomolecular conjugates with QDs can be obtained which are stable in biological environments. Energy transfer with these ligands is maximized by minimizing distances between QDs/nanoparticles and donors/acceptors directly attached to the ligands or assembled on their surfaces.

    Abstract: An improved method to produce artificial light for plant cultivation, an illumination device with a semiconductor light emission solution and device suited for plant cultivation in a greenhouse environment are described. The best mode is considered to be a lighting device with binary alloy quantum dots (110, 120, 130, 140, 150, 160) made by colloidal methods to produce a size distribution of quantum dots that produces an emission spectrum similar to the photosynthetically active radiation (PAR) spectrum. The methods and arrangements allow more precise spectral tuning of the emission spectrum for lights used in plant (310, 311) cultivation. Therefore unexpected improvements in the photomorphogenetic control of plant growth, and further improvements in plant production are realized.
