    • The present invention is directed to a luminescent waveguide device, and methods of making thereof, that may be used to convert solar energy into electricity. In particular, the present invention relates to extracting and waveguiding luminescence generated in a scattering medium so as to improve luminescent concentrator performance. By stacking one or a pair of transparent plates of refractive index slightly smaller than that of luminescent plate but still larger than that of air, a much greater fraction of re-emitted light by the embedded luminescent particles can be extracted so that the detrimental effect of particle scattering can be minimized. Additionally, by additionally using a high-efficiency diffractive optic component in the structure to redirect the re-emitted photons with angles falling into the escape zone to much larger angles so these otherwise outgoing photons can be waveguided by total internal reflection. These improvements minimize the critical-angle loss and increase the output light intensity at the ends of the waveguide.
    • 本发明涉及可用于将太阳能转换成电的发光波导装置及其制造方法。 特别地,本发明涉及提取和波导散射介质中产生的发光,从而提高发光浓缩器性能。 通过堆叠折射率略小于发光板的一个或一对折射率的透明板,但仍大于空气的透明板,可以提取由嵌入的发光粒子重新发射的光的大部分,从而使得不利的 粒子散射可以最小化。 另外,通过在该结构中另外使用高效率的衍射光学部件来将具有落入逃逸区域的角度的重新发射的光子重定向到更大的角度,因此这些另外的出射的光子可以被全内反射波导。 这些改进使临界角损失最小化并增加波导末端处的输出光强度。

    • A photoluminescence color display comprises a display panel that displays red, green and blue pixel areas, an excitation source operable to generate excitation radiation for operating the display, and a photoluminescence color-element plate. The color-element plate comprises at least one photoluminescence material, such as a phosphor material or quantum dots, that is operable to emit light corresponding to red, green and blue pixel areas of the display in response to said excitation radiation. Additionally, the photo-luminescence color display comprises a wavelength selective filter that is provided between the color-element plate and the excitation source. The filter has a transmission characteristic that allows the passage of excitation radiation from the excitation source to excite the at least one photoluminescence material whilst preventing the passage of photoluminescence light back to the excitation source thereby prevent cross contamination of light among the different pixel areas of the display.
