Abstract:
PROBLEM TO BE SOLVED: To provide an electron-emitting film, emitting uniform electrons at low field intensity and capable f being manufactured at a relatively low temperature. SOLUTION: The forming method of an electron-emitting film includes the following stages: (i) a graphite source 120 is vaporized in a cathode arc adhered device 100 to generate carbon plasma 170. (ii) a potential difference is applied between the graphite source 120 and a glass or silicone adhered substrate 130 to accelerate the carbon plasma 170 toward the adhered substrate 130. (iii) working gas is provided in the cathode arc adhered device 100. (iiii) the carbon plasma 170 is adhered onto the adhered substrate 130.
Abstract:
A method for forming an electron emissive film (200, 730, 830) includes the steps of: (i) evaporating a graphite source (120, 620) in a cathodic arc deposition apparatus (100, 600) to create a carbon plasma (170, 670), (ii) applying a potential difference between the graphite source (120, 620) and a glass or silicon deposition substrate (130, 630, 710, 810) for accelerating the carbon plasma (170, 670) toward the deposition substrate (130, 630, 710, 810), (iii) providing a working gas within the cathodic arc deposition apparatus (100, 600), and (ii) depositing the carbon plasma (170, 670) onto the deposition substrate (130, 630, 710, 810).

Abstract:
A power source (212) is disclosed for charging a battery (330) within a portable electronic device (310). An apparatus (422), such as a photovoltaic or thermoelectric cell, for charging the battery (330) is disposed contiguous to and within a transparent housing (412) of the portable electronic device (310). A fluorescent species (416), such as quantum dots or a fluorescent dye, is disposed on a side of the housing (412) opposed to the apparatus (422). Light (430) striking the fluorescent species (416) is converted into photons (432, 434) having a narrower spectrum that passes through the housing (412) to the apparatus (422). An optional layer (418) may be disposed on the fluorescent species (416) that reflects light from the fluorescent species (416) to the apparatus (422). Photonic crystals (415) may be combined with the fluorescent species (416) to increase reflectivity.
