Abstract: A method for making iridium oxide nanoparticles includes dissolving an iridium salt to obtain a salt-containing solution, mixing a complexing agent with the salt-containing solution to obtain a blend solution, and adding an oxidating agent to the blend solution to obtain a product mixture. A molar ratio of a complexing compound of the complexing agent to the iridium salt is controlled in a predetermined range so as to permit the product mixture to include iridium oxide nanoparticles.

Abstract: A method includes forming a first low-dimensional layer over an isolation layer, forming a first insulator over the first low-dimensional layer, forming a second low-dimensional layer over the first insulator, forming a second insulator over the second low-dimensional layer, and patterning the first low-dimensional layer, the first insulator, the second low-dimensional layer, and the second insulator into a protruding fin. Remaining portions of the first low-dimensional layer, the first insulator, the second low-dimensional layer, and the second insulator form a first low-dimensional strip, a first insulator strip, a second low-dimensional strip, and a second insulator strip, respectively. A transistor is then formed based on the protruding fin.

Abstract: The present invention relates to a white light source, and particularly to a white light source with crystal fiber and a method for color temperature tuning thereof. The white light source of the present invention comprises a pumping source for providing a first-color light, and a gradient index lens for coupling the first-color light into a crystal fiber. The crystal fiber absorbs a portion of the first-color light and generates a second-color light and a third-color light, and a white light with high color rendering index can be obtained. The crystal fiber is made of a first rare earth element oxide and a second rare earth element oxide co-doped yttrium aluminum garnet. The color temperature of the white light can be tuned by adjusting the position of the focus of the pumping light on the end section of the crystal fiber.
