  • Patterned sapphire substrate, light emitting diode and fabrication method thereof
    Patent number: 10312409
    Abstract: A patterned sapphire substrate has a first surface and a second surface opposite to each other, in which, the first surface of the substrate is formed by arranging a plurality of interspaced patterns, wherein, the patterns have a top surface, a bottom surface and a plurality of side surfaces and at least one concave region sandwiched between the adjacent side surfaces and the top surface, where, depth and width of the concave region gradually decrease from the top to the bottom of the pattern. The concave region on the pattern surface of the patterned sapphire substrate enlarges light reflection area, thus improving light extraction efficiency of the patterned sapphire substrate.
    Type: Grant

  • Preparation method of silver nanowires
    Patent number: 9393624
    Abstract: A preparation method of silver nanowires is provided. First, droplets of an ethylene glycol solution of silver nitrate is atomized by ultra-sonication and then added into a heated solution containing polyvinylpyrrolidone and sodium chloride to form silver nanowires. Comparing with the method without the ultra-sonication, the above method can increase the yield and the aspect ratio of the silver nanowires.
