    Abstract: A masked photocathode is provided having on a radiation transmissive support a mask pattern of a material that absorbs or reflects sensitizing radiation, particularly in the ultraviolet. In one form, the mask is formed in a process that includes at least partial oxidation of a metal layer pattern. Alternatively, a mask pattern that blocks all radiation with high reflectivity may be formed by employing a metal with a subsequent insulating layer, such as of an oxide of the metal or a separately deposited insulator, for protection from the photocathode. In another form the photoemissive layer may be deposited directly on the transmissive support and have on its surface a pattern of organic material to provide the mask for electrons on the target side of the cathode as well as to prevent any radiation reflected from the target from impinging on areas from which photoemission is not desired.

    Abstract: A photoelectron emitting member having a multiplex structure comprises a matrix and a protective film, said matrix being selected from the group consisting of elements, inorganic compounds, alloys, mixtures thereof and composites thereof which emit photoelectrons upon exposure to uv rays and other forms of radiation, said protective film compris­ing at least one material selected from the group consisting of metals, metallic compounds, plastics, polycyclic aromatic hydrocarbons, derivatives thereof or a mixture thereof which is film-forming and not thicker than 0.2 µm. The member can be used in a consistent way over a prolonged period as well as being capable of effective emission of photoelectrons. Fine particles electrically charged with photoelectrons which are emitted upon applying uv rays and/or other forms of radiation to the photoelectron emitting member, can be used in various applications such as (a) separation and classification of fine particles, as well as modifying their surfaces and controlling an electrically charged amount thereof; (b) the measurement of the concentration and size of fine particles in gases such as air and waste gases by using electrically charged fine particles; and (c) trapping and removal of charged fine particles to produce clean gases.

    Abstract: A photoelectron emitting member and method of electrically charging fine particles with photoelectrons, wherein the member includes a matrix that is at least composed of a material capable of transmitting ultraviolet rays and a material that is provided on the surface of the matrix or in its neighborhood and which emits photoelectrons upon irradiation with ultraviolet rays or sunlight. The member emitting photoelectrons upon irradiation with ultraviolet rays or sunlight is disposed in an electric field from the side opposite to the irradiated side. The member permits efficient utilization of the energy of ultraviolet rays. When sunlight is applied to the member to have it emit photoelectrons, particles can be electrically charged with energy costs being reduced to substantially zero.

    Abstract: A photo cathode used for an electron image projection apparatus has a silver layer as a photo electric material and a layer of an alkali metal or alkaline earth metal, such as cesium, coated on the silver layer. The cesium is as thick as several atomic layers, and reduces the work function of the photo cathode. The silver layer may be coated all over a substrate, and portions other than the cathode may be masked by a non photoelectric metal, or non transparent metal, such as platinum. Or, the silver layer may be patterned on the layer of a non photoelectric metal coated on the substrate. An excitation light to the photo cathode may be irradiated onto the surface of the silver, or onto the back of the silver layer through a transparent substrate. After depositing the cesium layer on the silver, the layers are heated in a vacuum at 50.degree. to 200.degree. C., thus a contrast ratio, i.e. ratio of electron current from the cathode and from the non cathode portion, is achieved as high as 20. This low temperature heat processing prevents lateral diffusion of the mask metal, resulting in a sharp edge of the cathode pattern. Silver and the cesium thereon are not susceptive to open air atmosphere, thus allowing long life and easy handling for an efficient lithography processing. The low absorption edge of the silver allows the use of a high pressure mercury lamp whose light is easily focused by a lens.
