Luminescent properties of Sr5(PO4)3 Cl:Eu2+, Mn2+ as a potential phosphor for UV-LED-based white LEDs

First-principles study on structural, electronic, vibrational and thermodynamic properties of Sr10(PO4)6X2(X = F, Cl, Br)

“…Firstly, Sr 10 (PO 4 ) 6 X 2 (X ¼ F, Cl, Br) are well-known hosts for functional rare earth ions with subsequent applications as uorescent and laser materials. [24][25][26][27][28][29][30] Secondly, Sr 10 (PO 4 ) 6 F 2 (Sr-FAP) is of interest in biological elds because of the ready entry of Sr into the food chain and its subsequent incorporation in bone. [31][32][33][34] Thirdly, as the member of apatite family, Sr 10 (PO 4 ) 6 X 2 (X ¼ F, Cl, Br) are considered to be suitable for nuclear waste storage, such as the glass encapsulated Sr 10 (PO 4 ) 6 Cl 2 (Sr-ClAP) can immobilize most of the radwaste elements in the composite matrix.…”

Photoluminescence characterization of Ce3+ and Dy3+ doped Li2CaGeO4 phosphors

“…Recently, UV (350-410 nm) LED chip mounted with blue, red, green or blue, yellow phosphor is considered as a promising white light generation way [2,3]. However, the samples in the previous works were fabricated by mixing two or three different phases of phosphors, leading to both a decrease in luminous efficiency due to re-absorption and poor reproducibility [4]. Thus, a single-phased phosphor for UVpumped white LED is required to enhance luminous efficiency and reproducibility of white LED.…”

Promotion of Mesoporous Vanadium Carbide Incorporated on Resorcinol–Formaldehyde Resin Carbon Composites with High‐Surface‐Areas on Platinum Catalysts for Methanol Electrooxidation

“…The d–d transition in Mn 2+ is forbidden and difficult to be pumped whereas Eu 2+ has been demonstrated to be an efficient sensitizer for Mn 2+ . Guo et al reported energy transfer between Eu 2+ and Mn 2+ in the host Sr 5 (PO 4 ) 3 Cl 11. They also reported Eu 2+ ‐ and Mn 2+ ‐co‐doped Ca 5 (PO 4 ) 3 Cl with blue and orange double band emission 12.…”
