PHOSPHOR FOR VACUUM ULTRAVIOLET-EXCITABLE LUMINOUS ELEMENT

摘要

PROBLEM TO BE SOLVED: To obtain a green light emitting phosphor for a vacuum ultraviolet- excitable element such as a plasma display panel(PDP) good in luminous sufficiency and a vacuum, ultraviolet-excitable element sing the phosphor. SOLUTION: (1) This phosphor for a vacuum ultraviolet-excitable luminous element is characterized by being represented by the general formula Gd1-aTbaAlO3 (0.003<=a<=0.5) (2) The vacuum ultraviolet-excitable luminous element is characterized as comprising the phosphor described in the above (1).
