摘要： A phosphor heat-treating method and an apparatus therefor capable of providing a phosphor exhibiting improved crystallizability and increased in concentration of a luminous center therein. A phosphor is heated and rapidly cooled in atmosphere gas of a predetermined pressure. The pressure substantially restrains decomposition and scattering of the phosphor during heating and cooling of the phosphor.

摘要： A low-velocity electron excited phosphor capable of exhibiting increased luminance and a method for producing the same. A matrix crystal for the phosphor is doped therein with an activator at implantation energy of 50 KeV by ion implantation, resulting in the activator entering a portion of the matrix crystal extending to a depth as small as 0.5 .mu.m from a surface thereof. Then, the phosphor is annealed for a reduced period of time as short as 10 seconds at a temperature of 900.degree. C. Such short-time annealing effectively prevents distribution of the activator in the matrix crystal formed during the implantation from being deeply spread into the matrix crystal by thermal diffusion. Thus, the activator concentratedly exists at only a portion of the matrix crystal in proximity to the surface thereof. Thus, the phosphor exhibits increased luminance as compared with a prior art, because luminescence of the phosphor is limited to the portion thereof in proximity to the surface.

摘要： A phosphor capable of exhibiting luminescence with high efficiency by excitation due to impingement of electrons accelerated under an anode voltage of hundreds volts to about 2 kV thereon and a method for preparing the same are disclosed. Mn is ion-implanted in ZnGa.sub.2 O.sub.4 which is a matrix crystal of the phosphor deposited on a substrate. Three kinds of implantation energy of 150 keV, 90 keV and 30 keV are selected and the ion implantation is effected three times in the order of the level of the implantation energy. A concentration of Mn is rendered substantially constant within a depth range between 100 angstrom and 1000 angstrom of a depth of 2000 angstrom or less in a luminous region of the phosphor. The ion implantation thus carried out three times permits the phosphor to exhibit increased luminous efficiency as compared with one-time ion implantation. The ion implantation permits Mn acting as a luminous center to be dispersed over a desired depth of the phosphor, resulting in lattice defects in the phosphor being widely distributed, leading to a decrease in the concentration of defects in the phosphor.

摘要： A powder agitator used for an ion implantation device or an ionized beam deposition device capable of exhibiting satisfactory powder agitating characteristics and minimizing positive charging on powders. The powder agitator includes a base, a vessel for receiving powders therein, a plurality of supports for supporting the vessel on the base, and a pair of piezoelectric elements arranged on the supports and functioning as a vibration generating section. Application of a voltage to the piezoelectric elements causes the vessel to be oscillated in a direction of rotation of the vessel and a speed of oscillation of the vessel to be varied depending on a direction of oscillation of the vessel, resulting in agitating the powders in the vessel.

摘要： A fluorescent display tube is provided, which employs a non-evaporation type getter, instead of the evaporation-type Ba getter, whereby the serviceable life of the fluorescent substance containing SrTiO3 as a base component is prolonged. At least one or more elements selected from the group consisting of Zr, V, Fe, Ti, Ma, Mn, and La are used for the getter for fluorescent display tubes, each which employs a fluorescent substance containing SrTiO3 as a base component. This feature allows carbon series residual gases remaining in the tube to be removed, so that the serviceable operation can be prolonged.

摘要： A method for producing a phosphor made of luminous inorganic particles of a nanostructure which is capable of keeping a surface of the phosphor from being polluted by any by-product and controlling a particle diameter distribution of the phosphor as desired. A carbon material and an inorganic salt are mixed together to prepare a mixture, which is then heated, to thereby form an interlaminar compound. Then, the interlaminar compound is subject to a treatment using an eliminating agent, leading to production of luminous inorganic compound particles adhered to the carbon material.
