PLASMA ELEMENT CONTAINING MAGNESIUM OXIDE PARTICULATES WITH SPECIFIC NEGATIVE POLE LUMINESCENCE CHARACTERISTICS

摘要

PROBLEM TO BE SOLVED: To provide a plasma element which is excellent in discharge characteristics having a low discharge voltage and a short discharge lag time. SOLUTION: The plasma element is provided with a particulate layer 11 of magnesium oxide having no negative pole luminescence peak at a wavelength range of 300 nm or less and having a negative pole luminescence peak in a range of 350-500 nm and having at least one negative pole luminescence peak in a range of 550-650 nm and 700-800 nm in a discharge space between a front substrate 1 and a rear substrate 8, and demonstrates improved discharge characteristics such as a low discharge voltage and a reduced discharge uneven time duration or the like.
