Effects of boric acid on structural and luminescent properties of BaAl2O4:(Eu2+, Dy3+) phosphors

Abstract

Eu 2? /Dy 3? -codoped BaAl 2 O 4 phosphors were prepared by conventional solid-state reaction with boric acid flux.

Photoluminescence properties of Pb5(PO4)3Br:RE (RE = Dy3+, Eu3+ and Tb3+) phosphor synthesised using solid‐state method

“…The obtained CIE colour coordinates of Pb 5 (PO 4 ) 3 Br:Dy 3+ , Pb 5 (PO 4 ) 3 Br:DyEu 3+ and Pb 5 (PO 4 ) 3 Br:Tb 3+ phosphors are presented in Table 1. By mixing the three strong emissions at 480 nm from Pb 5 (PO 4 ) 3 Br:Dy 3+ phosphor, 547 nm from Pb 5 (PO 4 ) 3 Br:Tb 3+ phosphor and 395 nm from Pb 5 (PO 4 ) 3 Br:Eu 3+ phosphor defined by their colour coordinates, most of the parts of white shades within the triangle (shown by dark black lines) can be accessed, as shown in the Figure 11, and therefore the synthesised phosphor can be used for the development of white light‐emitting diodes [41–45].…”

Wet chemical synthesis of BiPO4:Eu3+ phosphor for w‐LED application

“…[ 25 ] The inset displays the strength of these two emission lines as a function of Eu 3+ concentration, as well as the fluctuation of the orange and red emission lines. [ 26 ]…”

“…[25] The inset displays the strength of these two emission lines as a function of Eu 3+ concentration, as well as the fluctuation of the orange and red emission lines. [26] In the schematic energy level diagram in Figure 6, the multiple electronic transitions of the BiPO 4 :Eu 3+ are shown. The higher energy transitions.…”

Synthesis and Photoluminescence Properties of Ca5(PO4)3F: Ln (Ln: Dy3+, Eu3+ and Sm3+) Phosphors for near UV-based solid state lighting

“…There were no noticeable variations in the location of the emission peaks across all Ca5(PO4)3F:xSm 3+ samples. The variation in emission intensity with Sm 3+ ion concentrations under 402 nm excitation [21]. The intensity of the emission increases initially, reaching a maximum at 0.5 mole % Sm 3+ ion, and then drops as the concentration climbs further.…”
