New Tricolor Phosphors for Gas Discharge Display

Abstract

sured to be 1.2-1.4 ~m/hr or approximately 10% of the vertical rate. This number must be used to correct mask opening size as determined from Eq. [5].

Synthesis and photoluminescence of Eu3+-doped (Y,Gd)BO3 phosphors by a mild hydrothermal process

“…Recently, borate materials have received special attention, in particular with regard to their optical properties [1][2][3], such as high vacuum ultraviolet (VUV) transparency, large electronic band gaps, chemical and environment stability, and exceptional optical damage thresholds. Among borate phosphors, (Y,Gd)BO 3 :Eu 3+ is one of the best phosphors available for the red primary of the color picture in plasma display panels and possible use in Hg-free lamp.…”

Photoluminescent properties of Sb3+-doped and (Sb3+, Eu3+) co-doped YBO3 phosphors prepared via hydrothermal method and solid-state process

“…Tb 3+ -activated YBO 3 and (Y, Gd)BO 3 PDP materials with green emission have also been reported by Rao [7], Sohn et al [8] and Jung et al [9]. Various methods have been used to prepare LnBO 3 phosphor materials, for example, conventional solid-state reaction [1,6,10], co-precipitation [11,12], microwave heating [13], spray pyrolysis [14], sol-gel [11], combustion [15], and hydrothermal method [16][17][18]. The phosphor of YBO 3 : Eu 3+ has been produced through a high temperature solidstate method in industry for many years.…”

“…Eu 3+ -doped LnBO 3 has been widely used as a red color material for plasma display panels (PDP) because of its high quantum efficiency and good color coordinates under 147 nm VUV irradiation [4][5][6]. Tb 3+ -activated YBO 3 and (Y, Gd)BO 3 PDP materials with green emission have also been reported by Rao [7], Sohn et al [8] and Jung et al [9].…”

Synthesis and morphology control of YBO₃:Tb³⁺ green phosphor by precipitation from homogeneous solution

“…3), 4) Since high pixelization of PDP is in progress, not only the luminescence characteristics such as internal quantum efficiency, emission and excitation wavelengths, but the characteristics as a powder (particle form, size, size distribution, dispersibility) are also important. Although the mainstream synthesis method of commercial phosphors is the solid-state reaction that fits mass production, phosphor synthesis is being performed in various ways in recent years for the improvement of its characteristics as a powder.…”
