A novel blue-emitting phosphor: BaAl2B2O7: Pb2+

Synthesis and photoluminescence properties of Pb2+ doped Ba2Be2B2O7

“…The photoluminescence properties of the Pb 2+ ion in various inorganic borates have been extensively investigated for many years [14][15][16][17][18][19][20][21][22][23][24][25][26]. So, the emission peak of Pb 2+ in these borate phosphors was usually observed in 300-450 nm spectral range.…”

“…This diversity is depending strongly on the site occupied by Pb 2+ ions, electronegativity of the ligand, crystal structure of the host lattice and temperature [23][24][25][26]. Up to now, the photoluminescence properties of Pb 2+ were investigated in various inorganic borates with different structure, such as BaB 2 O 4 [18], BaAl 2 B 2 O 7 [19], Ba 2 Mg(BO 3 ) 2 [20], LiBa 2 B 5 O 10 [21] with the intention of investigation the effect of crystal structure on the PL of Pb 2+ . As seen in Table 1, Pb 2+ ions occupy the Ba 2+ sites in these borates, which have different crystal structures, and the emission of Pb 2+ in these hosts is located at characteristically different positions due to the electronegativity of the ligands [22,26].…”

Synthesis and photoluminescence properties of Pb2+ doped Li4CaB2O6

“…Inorganic metal borate phosphors have interested much attention due to their high stability, easy synthesis, and high UV transparency [2]. Up to now, the luminescence properties of the Pb 2+ ion in inorganic metal borates have been extensively investigated by the scientists [3][4][5][6][7][8][9][10][11][12]. In these borates, the absorption and emission spectra of Pb 2+ are in the near UV-Vis spectral region depending strongly on the site occupied by Pb 2+ ions, electronegativity of the cation and crystal structure of the host lattice [11,12].…”

Synthesis and Photoluminescence Study of Bi3+and Pb2+Activated Ca3(BO3)2

“…Pb 2+ doped phosphors have been the interest of many researchers. Many attempts have been made to synthesize Pb 2+ activated phosphors which emit in varying range from 290 to 470 nm when excited by UV light [13][14][15][16][17][18][19][20][21][22]. In recent years, great efforts have been taken by many researchers to discover and develop new rare-earth and transition-metal ion-doped material systems as luminescent materials with high absorption in the UV spectral region [23].…”
