摘要： PURPOSE:To readily provide a cathode-ray tube having a phosphor film of high packing density by forming a viscous film on the inner surface of the face plate of the cathode-ray tube, forming layers of phosphor particles on the film, and fixing the layers of phosphor particles while increasing the packing density through vibration or the like. CONSTITUTION:A deliquescent inorganic compound (e.g. zinc chloride) is mixed with a water soluble polymer (e.g. polyvinyl alcohol) to manufacture a viscous liquid. The viscous liquid is applied to the inner surface of the face plate 21 of a cathode-ray tube to form a viscous film. Next, layers of phosphor particles are formed on the viscous film and the packing density of the layers of phosphor particles is increased by a vibrating method, etc. Adhesive properties are provided between the face plate 21 and one layer of phosphor particles and between the layers of phosphor particles and thereby the layers of phosphor particles are fixed so as to form a phosphor film 22. Then an Al-evaporated film 23 is formed by a normal method and baking is performed and a neck tube 24 and an electron gun 25 are mounted to manufacture a cathode-ray tube.

摘要： PURPOSE:When a thin film is formed through vapor-phase chemical reaction, the base plate is irradiated with a specific ion to give a semiconductor thin film of good electrical and optical properties. CONSTITUTION:The base plate is prepared by forming an Al2O3 thin film of about 2,000Angstrom on a glass plate by sputtering in an evacuated reactor 1. Then, Zn(C2H5)2 is introduced into the reactor and the pressure is adjusted to about 10 Torr. The base plate is kept at about 80 deg.C to effect deposition for about 2hr whereby a fine-crystal film composed of Zn, S and carbon compounds is formed in a thickness of about 7mu. The carbon remaining in the film is about 3X10 /cm . In the meantime, a film is formed under the same conditions and the film is simultaneously irradiated with H ions of 70eV accelerating voltage and 100nA/cm to form a hexagonal crystal film of ZnS of 1.3mu thickness more than 70%. The remaining crystal mainly has the cubic structure and the concentration of the remaining carbon is 2X10 /cm . Thus, crystal growth rate is doubled in comparison with the case of no ion irradiation and the carbon content is reduced by about 3 digits.

摘要： PURPOSE:To obtain a cathode ray tube using a blue light-emitting fluorescencer capable of improving the luminous color tone and electric current coefficient. CONSTITUTION:A silver-activated cubic zinc sulfide fluorescencer is mixed with a silver-activated hexagonal zinc sulfide fluorescencer at a suitable ratio. The resultant fluorescencer is then used to prepare a cathode ray tube. Both color tone and electric current efficiency of the cathode ray tube can be improved by providing the cathode ray tube with the blue fluorescencer capable of emitting deep blue light as a fluorescent film. The obtained cathode ray tube can be used to realize an improvement in the range in which the color tone is reproduced and the resolution of a color TV image receptor.

摘要： PURPOSE:To obtain a high purity and high quality thin film of a II-VI compd. crystal by a molecular beam epitaxial growth method by optimizing the temp. of a substrate and the molar ratio of fed starting material for a group VI element to fed starting material for a group II element so as to inhibit the entering of impurities and the occurrence of lattice defects. CONSTITUTION:When molecular beams are fed to the surface of a substrate 4 in a vacuum reactor 2 to form a thin film by a molecular beam epitaxial growth method, the molar ratio of fed starting material for a group VI element to fed starting material for a group II element is regulated to 0.7-3.3, the substrate 4 is kept at 220-400 deg.C and a thin film of a II-VI compd. crystal is formed. The hydride of a group VI element is used as the starting material for the group VI element and an org. compd. of zinc as the starting material for the group II element.

摘要： PURPOSE:To form such a light emitting layer that is high intensity, high efficiency and high reliability by making it contact with substrate which heated vapor of a specific compound of sulfur or selenium under the specified atmosphere. CONSTITUTION:Under the existence of vapor of di-pi-methylcyclopentadienyl manganese or di-pi-ethylcyclopentadienyl manganese, or hydrogen or helium containing vapor, vapor of die-thylzinc and at least one of diethyl sulfur, hydrogen sulfide, dimethyl selenium, diethyl selenium and selenic hydrogen is made contact with the substrate heated to a temperature of 100-390 deg.C. With this constitution, a manganese dope zinc chalcogenide light emitting layer of 0.3-0.8 wt.% in manganese content in the layer is formed on the substrate. Since relatively low temperature treatment takes place, constituent material is in no case deteriorated by heat.
