Synthesis and photoluminescence properties of Eu doped LiBaPO4 phosphors for solid state lighting

Structural, electronic, bonding and optical properties of LiBaPO4: A comparative study of monoclinic and trigonal phases

“…This leads to numerous applications of these compounds such as cathodes for batteries and as well as luminescent host material [1][2][3][4][5][6][7]. Divalent-monovalent cationic orthophosphates with general formula A II B I PO 4 (A=Ba 2+ and Sr 2+ ; B=Li + , Na + , K + , Rb + , Cs + ) are water insoluble and render several structure types depending on the size and coordination number (CN) of A and B atoms respectively [8][9][10][11][12][13]. However the calcium orthophosphate is sparingly soluble in water and has a lot of biomedical applications like biomimetics, bio mineralization and pathological calcification etc.…”

“…Some of these phosphates have been extensively studied due to their interesting ferroic properties like ferroelectricity in A II B I PO 4 (A=Ca, Zn, Sr, Cd, Ba, Pb; B=Na, K) and ferro elasticity in CsCoPO 4 and CsZnPO 4 compounds [16][17][18]. In last few years, ABPO 4 type orthophosphates such as LiBaPO 4 , NaBaPO 4 and LuPO 4 doped with rare earth ions (Eu 2+ , Ce 3+ , Tb 3+ , Dy 3+ , Sm 3+ , Tm 3+ ) have acquired a lot of attention for their potential applications as light emitting phosphors in solid state lightning and displays [8,19,20]. The majority of A II B I PO 4 orthophosphates have atomic arrangement closely related to that of tridymite [16].…”

Photoenergy Conversion Behaviors of Photoluminescence and Photocatalysis in Silver-Coated LiBaPO4:Eu2+

“…To verify the motivations, LiBaPO 4 :Eu 2+ with an optimal doping concentration of 5.0 mol % was prepared in this work via a facile solid-state reaction method. In recent years, various topics have been reported for RE-doped LiBaPO 4 , including LiBaPO 4 :Eu 2+ , − LiBaPO 4 :Eu 3+ , LiBaPO 4 :Eu 2+ , Pr 3+ , LiBaPO 4 :Sm 3+ , LiBaPO 4 :Dy 3+ , LiBaPO 4 :Bi 3+ , LiBaPO 4 :RE (RE = Eu 2+ , Tb 3+ , Sm 3+ ), LiBaPO 4 :Tb 3+ , Ce 3+ , LiBaPO 4 :M 3+ (M = Eu and Dy) . These phosphors are suggested to have potential applications in solid-state lighting as new white light-emitting diodes.…”

“…To verify the motivations, LiBaPO 4 :Eu 2+ with an optimal doping concentration of 5.0 mol % 11 was prepared in this work via a facile solid-state reaction method. In recent years, various topics have been reported for RE-doped LiBaPO 4 , including LiBaPO 4 :Eu 2+ , 11−14 LiBaPO 4 :Eu 3+ ,15 LiBaPO 4 :Eu 2+ , Pr 3+ ,16 LiBaPO 4 :Sm 3+ ,17 LiBa-PO 4 :Dy 3+ ,18 LiBaPO 4 :Bi 3+ ,19 LiBaPO 4 :RE (RE = Eu 2+ , Tb 3+ , Sm 3+…”

Realizing near white and warm light emission of cuprous iodide complexes by alkyl-isomerization of ligands

“…[12][13][14][15][16][17] In order to adjust the light quality which is the lack of the first method, there also combine UV-emitting LED chips with phosphors or mix with phosphors of other colors (red, green, and blue). [18][19][20][21][22][23] However, all the above phosphors are dominated by rare earth element phosphors. [24][25][26][27][28][29][30][31][32][33] Due to the potential cost and supply risks of rare earth elements, and their negative impact on the environment and human health, it is critical to develop some low-cost, high-performance, and rare earth element-free phosphors.…”
