摘要： A phosphor host compound is produced from a host compound material. Then, the host compound and a trivalent europium compound are reacted in a reducing atmosphere to generate a desired divalent europium-activated phosphor. If the divalent europium-activated phosphor is generated in this manner, a chemical reaction between the raw material for the host compound and the trivalent europium compound can be suppressed. Therefore, variations in the luminescent color among different production lots of the phosphor can be suppressed, and a phosphor with high color purity can be provided with high repeatability.

摘要： A method for producing a trivalent rare earth ion-containing aluminate phosphor includes preparing a phosphor raw material comprising a granular aluminum containing compound in a phosphor raw material production process, heating the phosphor raw material in an oxidizing atmosphere at a predetermined temperature (e.g., 1500° C. to 1800° C.) so as to produce an intermediate phosphor in an intermediate phosphor production process. After the intermediate phosphor is cracked, the intermediate phosphor is heated in a reducing atmosphere at a predetermined temperature (e.g., 1400° C. to 1800° C.) in a trivalent rare earth ion-containing aluminate phosphor production process. The heating temperature in a reducing atmosphere is equal to or less than the heating temperature in an oxidizing atmosphere. A post treatment is performed, if necessary. Thus, a trivalent rare earth ion-containing aluminate phosphor can be obtained.

摘要： A display device includes an ambient light sensor positioned adjacent a display screen so as to confront an occupant in front of the display device, and a luminance level setting unit for inputting a desired luminance level. An output from the ambient light sensor is fed to a screen luminance calculating unit for calculating the adjustable range of screen luminance to be adjusted on the basis of an output signal from the ambient light sensor. A luminance determining unit determines a proper screen luminance based on an output signal from the screen luminance calculating unit and an output signal from the luminance level setting unit. A screen luminance control unit operates in response to an output signal from the luminance determining unit to adjust the screen luminance to the proper screen luminance.
