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

A high efficiency blue phosphor BaCa2MgSi2O8:Eu2+under VUV and UV excitation

“…6,7 Consequently, how to improve the luminous efficiency and stability of blue phosphors has been one of the critical issues for developing PDPs, [8][9][10][11] and great efforts are being made to search for new blue-emitting phosphors. [12][13][14] Eu 2+ ion has 4f 7 ground state and the excited state is 4f 6 5d. Excitation and emission bands of Eu 2+ are usually broad due to parity allowed 4f 7 -4f 6 5d transitions.…”

Luminescence properties of Eu2+-doped BaSi2O5 as an efficient green phosphor for light-emitting devices and wide color gamut field emission displays

“…Because of the excellent luminescence properties, Eu 2+ doped phosphors have been studied for their actual or promising applications in LEDs, tricolor fluorescence lamps and plasma display panels (PDPs). [31][32][33] [34][35][36] Silicates, as the most important class of compounds, have been widely used as the matrix of inorganic phosphors due to their merits, namely facile synthesis, high chemical stability, good thermal quenching and ideal excitation and emission wavelengths. [37][38][39][40][41] As a member of the silicate host, BaSi 2 O 5 has attracted attention and related work which aims to value the potential inorganic phosphor has been carried out.…”

Electronic structures and Eu3+ photoluminescence behaviors in Y2Si2O7 and La2Si2O7

“…In addition, there are some other fatal drawbacks such as poor color purity for the commercial red phosphor (Gd, Y)BO 3 :Eu 3+ , too long decay time for the green Zn 2 SiO 4 :Mn 2+ and low degradation stability for the blue BaMgAl 10 O 17 :Eu 2+ [9][10][11]. In order to solve these problems, considerable research activities such as empirical doping, morphology modification, fabrication process improving as well as new phosphors exploring [12][13][14][15][16][17][18] have been made during the past few years. Despite all these efforts, the premium solution to the major problems mentioned above is to develop a better understanding of the VUV photoluminescence (PL) mechnisms.…”
