Embodiment 6

[0438] In embodiment 6, the green phosphor material used is Zn 2 SiO 4 :Mn 2+ (Mn content is 2.3% by weight), the red phosphor is YBO 3 :Eu 3+ (Eu 3+ The substitution amount for the Y element is 0.1).

[0439] In embodiment 6, the blue phosphor material used is BaMgAl 10 o 17 :Eu 2+ , Eu 2+ The amount of substitution of ions for the Ba element in the matrix material is as shown in Nos. 601 to 604 in Table 11, which are 0.5, 2.0, 5.0 and 8.0 at%, respectively.

[0440] In Table 11, the composition of the blue phosphor material is Ba 1-x MgAl 10 o 17 :Eu x . It is with BaMgAl 10 o 17 :Eu 2+ Same phosphor, but expressing Eu 2+ The x value of the amount of substitution of ions for the Ba element in the matrix material is as described in the formula.

Abstract

The plasma display panel of the present invention has, for achieving high luminance and high reliability, a plurality of discharge spaces formed between a front panel and a back panel that are disposed to oppose each other, and phosphor layers, formed in the discharge spaces, each including phosphor particles of one of blue, red and green colors, wherein the phosphor particles of at least one of blue, red and green colors included in the phosphor layer are flake-like particles.

Description

[0001] This application is a divisional application of a Chinese patent application with a filing date of November 5, 1998, an application number of CN 98812908.6, and an invention title of "Phosphor Material, Phosphor Material, Plasma Display and Manufacturing Method thereof". technical field [0002] The present invention relates to phosphor materials and phosphor materials capable of emitting light efficiently, plasma displays used for display devices and the like, and their manufacturing methods. Background technique [0003] In the past, CRTs were generally used as TV monitors. Although CRTs are superior to plasma displays and liquid crystals in terms of resolution and image quality, they are not suitable for large screens over 40 inches in terms of thickness and weight. In addition, liquid crystal has good performance of low power consumption and low driving voltage, but the size and viewing angle of the screen are limited. [0004] Different from the above situation, ...
