“…Open-frameworks containing extra-large channels are of great importance in many fields of research as ion exchangers, catalysts, medical MRI reagents, low-k materials, zeolite-dye microlasers [1,2] , as well as their use in hydrogen gas storage and photoluminescent materials recently [3,4] . Among the increasingly synthesized frameworks, the system of metal phosphates and phosphites has shown a greater disposition to form extra-large-pore structures [5][6][7][8] .…”

An open-framework zinc-cobalt phosphate CoZnPO 4 -V with 16-ring extra-large-pore channels has been obtained in the presence of chain-type polyamines as the structure directing agent (SDA). Its large single crystal suited for structure refinement has been prepared with the assistance of small organic amines. Single-crystal X-ray diffraction analysis has shown that CoZnPO 4 -V is a novel metal phosphate. It crystallizes in monoclinic space group P2 1 /c (No. 14), with a = 31.936(3) Å, b = 8.3775(7) Å, c = 15.7874(13) Å, α = γ = 90°, β = 97.0530(10)°, V = 4191.8(6) Å 3 , and Z = 4 with R 1 = 0.0455，wR 2 = 0.0869. Its three-dimensional framework can be considered as stacking from two-dimensional nets and onedimensional units as linkers. Between the stacking nets and linkers are located extra-large channels with 16-ring apertures.zinc-cobalt phosphate, chain-type polyamines, structure directing agent, small organic amine

“…W-LEDs have been fabricated by the combination of red, green and blue tri-phosphor powders, which can be excited by near ultraviolet light [1,2] . However, W-LEDs prepared by mixed phosphors matrix have some inevitably disadvantages, such as low luminescence, color reproduction, unstable ratio control and so on.…”

A novel series of color-tunable single-phased phosphors La 1-x-y PO 4 :xEu 3+ /yTb 3+ (x=0, 0.01, 0.02, 0.03, 0.04, 0.05; y=0, 0.05, 0.10, 0.15, 0.20) was synthesized via co-precipitation method with diammonium hydrogen phosphate as precipitant. The morphology, crystal structure and photoluminescence properties of the as-prepared samples were characterized by means of X-ray diffraction(XRD), scanning electron microscopy(SEM) and fluorescence spectrophotometer. The results reveal that the as-synthesized samples calcined at 1100 °C display spherical morphology with uniform distribution. Upon excitation with 350 nm ultraviolet radiation, the LaPO 4 :Eu 3+ /Tb 3+ phosphors showed a green light peaking at 543 nm assigned to the characteristic 5 D 4 -7 F 5 emission of Tb 3+ and a red light peaking at 591 nm corresponding to the characteristic 5 D 0 -7 F 1 emission of Eu 3+ simultaneously. For the Eu 3+ /Tb 3+ co-activated phosphors, Tb 3+ acts as an efficient sensitizer to enhance the emission intensity of Eu 3+ ions. The energy transfer mechanism and the emission color tunability of LaPO 4 :Eu 3+ /Tb 3+ have been studied. The results indicate that a color-tunable luminescence(from green to white to red) can be achieved by adjusting the Eu 3+ /Tb 3+ doping ratio in the LaPO 4 host matrix.
