Origin of PL intensity increase of CaMgSi2O6:Eu2+ phosphor after baking process for PDPs application

Blue luminescence of nanocrystalline CaZrO3:Tm phosphors synthesized by a modified Pechini sol–gel method

“…In order to further confirm the assignments of these two peaks, the excitation spectrum ( Fig. 3(b)) of pure CaZrO 3 prepared by the same method as CaZrO 3 :Tm was measured, which also consists of two peaks located at the same position as CaZrO 3 that the band gap of CaZrO 3 was around 200 nm, which was consistent with the previously reported results (206 nm, about 6.1 eV) [20]. Furthermore, Kaneyoshi also found the similar peak in bulk CaZrO 3 [21].…”

“…The conventional blue phosphor BaMgAl 10 O 17 :Eu (BAM:Eu) is an important blue phosphor, which has been used widely as blue-color emitting phosphors and plasma display panel (PDP). But there are some related researches that indicated that BAM:Eu still has some drawbacks [3,4]. For example, BAM:Eu significantly loses the radiation efficiency, and simultaneously accompanies a color shift during the thermal treatment at the temperature of 450-550 1C [5,6].…”

Luminescence enhancement of Eu-doped calcium magnesium silicate blue phosphor for UV-LED application

“…Calcium magnesium silicate (CMS, CaMgSi 2 O 6 ) has been studied as a host for long-lasting phosphor and plasma display panels (PDPs) [9][10][11]. The Eu 2+ -doped CaMgSi 2 O 6 (CMS:Eu) is an efficient phosphor that emits blue light by the stimulation of ultraviolet or vacuum ultraviolet (VUV) [9].…”

“…Conventionally, the CMS phosphor was prepared by a solidstate route [11,13]. The luminescence intensity of CMS:Eu 2+ phosphor was reported to be affected by the Si quantity [13][14][15].…”

Novel blue-emitting phosphor Sr2.979Eu0.021Al10−xBxSiO20 (x=0, 0.25, 0.5, 0.75 and 1) for PDP applications

“…The other one is to substitute rare earth ion in BAM for reduction of the damage caused by VUV irradiation. In another way to solve this problem is to make a new blue phosphor [7][8][9]. Recently, Sr 3 Al 10 SiO 20 :Eu 2+ blue phosphor has been synthesized and studied the PL property under VUV excitation [10].…”
