  • Publication number: 20140333908
    Abstract: The disclosure provides a method for regulating a light wavelength of a projection device. The method comprises the following steps. A single-color light source is provided and emits a first chromatic light. A phosphor layer is formed on an optical path of the single-color light source, so that the first chromatic light transmits the phosphor layer. The phosphor layer transforms a part of the first chromatic light to a second chromatic light, and emits the residual first chromatic light. The residual first chromatic light is further mixed with the second chromatic light to generate a third chromatic light. The wavelength of the third chromatic light is regulated by adjusting the proportion of the luminous intensity of the residual first chromatic light and the second chromatic light.

  • Patent number: 8460427
    Abstract: A method for manufacturing metal nano particles having a hollow structure is provided. First, a suitable reducing agent is added into a first metal salt solution, and first metal ions are reduced to form first metal nano particles. Next, after the reducing agent is decomposed, a second metal salt solution with a higher reduction potential than that of the first metal is added. Then, the first metal particles are oxidized to form first metal ions when the second metal ions are reduced on the surface of the first metal by electrochemical oxidation reduction reaction, and thus, second metal nano particles having a hollow structure and a larger surface area are obtained. The method is simple and the metal nano particles with uniform particle size are obtained by this method.
