“…Apatite-type alkaline-earth halophosphates with the general formula of M 5 (PO 4 ) 3 Cl (M = Ca, Sr, Ba) as host of luminescence materials have been widely investigated because of the flexibility of host lattice, good thermal stability, cheap raw materials, and simple synthesis conditions. − In the M 5 (PO 4 ) 3 Cl structure, there are two types of cationic sites (M1 and M2), which are the 6-fold coordinated 4f sites and 7-fold coordinated 4h sites, respectively . Both sites are suitable and easily accommodate a great variety of foreign cations, for example, rare earth ions, transition metal ions, and alkaline earth ions with different ionic radii, which make it possible to design a novel luminescence material.…”

A series of single-phased (Sr3-x,Ca1-y-z,Ba)(PO4)3Cl (SCBPO_Cl):xEu(2+), yTb(3+), zMn(2+) phosphors were synthesized by high-temperature solid-state reaction, and luminescent properties of these phosphors were investigated by means of photoluminescence and microcathode luminescence (μ-CL). Under UV excitation, white-light emission was obtained from triactivated SCBPO_Cl phosphors via combining three emission bands centered at 450, 543, and 570 nm contributed by Eu(2+), Tb(3+), and Mn(2+), respectively. White-light emission with the three emission bands is further demonstrated in the fluorescence microscope images, CL spectrum, and μ-CL mappings, which strongly confirm that the luminescence distribution of as-prepared SCBPO_Cl:xEu(2+), yTb(3+), zMn(2+) phosphors is very homogeneous. Both spectral overlapping and lifetime decay analyses suggest that dual energy transfers, that is, Eu(2+)→Tb(3+) and Eu(2+)→Mn(2+), play key roles in obtaining the white emission. The International Commission on Illumination value of white emission as well as luminescence quantum yield (51.2-81.4%) can be tuned by precisely controlling the content of Eu(2+), Tb(3+), and Mn(2+). These results suggest that this single-phased SCBPO_Cl:xEu(2+), yTb(3+), zMn(2+) phosphor may have a potential application as a near-UV convertible white-light emission phosphor for phosphor-converted white light-emitting diode.

“…Over the past several decades, rear earth ions (RE 3+ ) doped phosphors have attracted much attention due to their potential applications in plasma display panels (PDPs), field emission displays (FEDs), fluorescent lamps and so on [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In recent years, with the technical mature of GaN-based LEDs, it is possible to achieve solid state illumination by combining short wavelength GaN-based LED chips with tricolor phosphors.…”

“…The third approach is using near ultraviolet (NUV) or blue LED sources to excite bi-or tri-colour phosphors to generate white light. Recently, we have reported some inorganic phosphors for lamp industry applications, such as silicate (9), tungstate (10,11), vanadates (12,13), sulphates (14)(15)(16)(17)(18)(19), borates (20), oxides (21), aluminates (22)(23)(24), sulphides (25)(26)(27), halophosphors (28)(29)(30)(31) and phosphates (32)(33)(34)(35)(36)(37)(38)(39)(40).

Eu(2+)-activated SrMg(2)Al(16)O(27) novel phosphor was synthesized by a combustion method (550°C furnace). The prepared phosphor was first characterized by X-ray diffraction (XRD) for confirmation of phase purity. SEM analysis showed the morphology of the phosphor. The photoluminescence characteristics showed broad-band excitation at 324 nm, which was monitored at 465 nm emission wavelength. The SrMg(2)Al(16)O(27):Eu(2+) phosphor shows broad blue emission centred at 465 nm, emitting a blue light corresponding to 4f(6) 5d(1) → 4f(7) transition. Here we report the photoluminescence characteristics of the prepared phosphor and compare it with commercial BAM:Eu(2+) phosphor.
