Title: Emission screen and its manufacture
IPC: H01J9/22
Filed: 1988-04-20
Abstract: PURPOSE:To obtain the fluorescent film in which the draw-out effectiveness of emission nears that of the fluorescent film of a powder and the surface has an excellent heat conductivity like a thin film by forming the fine thin film having an excellent heat conductivity on the substrate on which a fluorescent powder is applied.

IPC: H01S5/00
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To increase luminous efficiency by specifically suppressing the excitation of phonons and other electrons in a quantum box, and increasing the rate pf relaxation performed by a luminous process. SOLUTION: First of all, constitution is so made as to satisfy inequality I, to suppress phonon emission in a relaxing process from an intermediate level E2 to a lower level E1 in a quantum box. Next, the intervals between quantum levels are determined so as to satisfy inequality II, to suppress a process of being excited from the intermediate level E2 to an upper level E3. In inequalities I, II, E2-E1, E3-E2 represent level intervals, and hωopt represents the energy of lattice vibration, and Δ1 and Δ2 are 4 meV. By raising, in this way, the rate of relaxation performed by a luminous process in the relaxing process from the intermediate level E2 to the lower level E1 in the quantum box, a quantum box having a high luminous efficiency is obtained.  Besides, an infrared light emitting element as a high-efficacy light source for infrared rays (the wavelength λ is approximately 25 μm) becomes available.
