Luminescence properties of red-emitting Ca9Y(PO4)7: Eu3+ phosphor for NUV white-LEDs

Layered Crystal Structure, Color-Tunable Photoluminescence, and Excellent Thermal Stability of MgIn2P4O14 Phosphate-Based Phosphors

“…The value of θ can be obtained by the slope (−θ/3) of the fitting line in the plot of log­( I / x ) versus log­( x ). As is shown in the inset of Figure c, the fitted slope is −1.79, that is, θ is closest to 6, shedding light on the fact that the resonant d–d interaction , is the crucial quenching mechanism for the MgIn 2 P 4 O 14 :Tm phosphors.…”

Monodisperse and hollow structured Y 2 O 3 :Ln 3+ (Ln = Eu, Dy, Er, Tm) nanospheres: A facile synthesis and multicolor-tunable luminescence properties

“…Rare earth ions (Ln 3+ ) doped luminescent materials have been extensively studied due to their unique electronic, optical, and chemical properties [13][14][15]. In particular, the Ln 3+ doped hollow down-conversion (DC) and up-conversion (UC) spheres should be applied in drug and enzyme delivery, and specific phosphor powder due to their distinct photophysical properties and structural characteristics [6,16,17].…”

The influence of charge compensation defects on the spectroscopic properties of europium doped Ca9Y(PO4)7

“…Ca 9 Y(PO 4 ) 7 belongs to the whitlockite family and can be described by the general formula: Ca 9 R(PO 4 ) 7 , where R ¼ Ln, Pr, Eu, Tb, Dy, Ho, Er, Y, Bi, Al, Lu. [12][13][14][15][16][17][18] The structural model of Ca 9 Y(PO 4 ) 7 was proposed by Golubev and Lazoryak 19 and the representation of the unit cell and coordination of the cation sites in Ca 9 Y(PO 4 ) 7 are shown in Fig. 1 and 2, respectively.…”
