“…This method and basis set was chosen because it worked well for H 2 PCN [1]. Using the ab initio spectroscopic constants, it was relatively easy to locate the microwave transitions of the normal and the minor isotopologues of cyanophosphaacetylene.…”

“…The most striking feature of the structure of cyanophosphaacetylene is the nonlinear PAC"C angle of 174°. The analogous angle, PAC"N, in H 2 PCN was determined to be 175° [1]. The nitrogen analog of H 2 PCN is cyanamide, H 2 NCN.…”

“…We recently published a pulsed-jet Fourier transform microwave (FTMW) study of cyanophosphine, H 2 PCN, the first spectroscopic study, at any wavelength, of this simple five-atom phosphine derivative [1]. Almost all the small molecules containing both phosphorous and carbon which have been studied by high resolution microwave spectroscopy involve multiple bonds between the carbon and the phosphorous, usually C"P, as presented in reference [1].…”

“…Almost all the small molecules containing both phosphorous and carbon which have been studied by high resolution microwave spectroscopy involve multiple bonds between the carbon and the phosphorous, usually C"P, as presented in reference [1]. The simple phosphine derivatives are as rare as hen's teeth in the microwave literature, perhaps because the syntheses are difficult with immediate rearrangement in basic medium, for example, N"CAPH 2 fi H 2 NAC"P [2].…”

“…3,4 Ming Kang team has done very deep research on rare-earth doping calcium carbonate phosphor, and has published many articles already. 5-8 When doped with Eu 3þ ions, the CaCO 3 phosphor shows redemission, 3 and Dy 3þ doped phosphor shows yellow-emission and blue-emission. Both of Eu 3þ and Dy 3þ ions have good luminescence characteristics under UV excitation.…”

Phosphors based on calcium carbonate, co-doped with various Eu 3þ and Dy 3þ concentrations were prepared by microwave coprecipitation method. The prepared phosphors were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry and differential scanning calorimetry (TG-DSC) and photoluminescence and photoluminescence excitation (PL-PLE) spectroscopy. Results showed that Dy 3þ and Eu 3þ ions were uniformly introduced into the host lattice of CaCO 3 taking the place of Ca 2þ ions. Under the excitation at 382 nm, the emission peak wavelengths were at 487 nm ( 4 F 9=2 ! 6 H 15=2 of Dy 3þ ), 576 nm ( 4 F 9=2 ! 6 H 13=2 of Dy 3þ ), and 614 nm ( 5 D 0 ! 7 F 2 of Eu 3þ ). The luminescent intensities and emitting colors of Eu 3þ -Dy 3þ co-doped CaCO 3 phosphors could be controlled by UV-violet excitations wavelengths or the rareearth ions concentrations of Eu 3þ and Dy 3þ in phosphors. The chromaticity coordinates and photographs of samples under UV light showed the changes of the luminescence color intuitively through the varing UV-violet excitations wavelengths or the rareearth ions concentrations of Eu 3þ and Dy 3þ .Recently, microwave irradiation has been widely applied to chemical synthesis. Compared with common methods, microwave irradiation synthesis is homogeneous, highly purity, and capable of shortening reaction time, making products with small particle size, narrowing particle size distribution. 1 For example, calcium carbonate, as host compound of rare-earth ions, can be synthesized by liquidphase reaction without calcining, 2 beyond that, microwave coprecipitation can be served as a useful method in affecting the nucleation, crystal growth, accelerating reaction process, and the final structure of material. 3,4 Ming Kang team has done very deep research on rare-earth doping calcium carbonate phosphor, and has published many articles already. 5-8 When doped with Eu 3þ ions, the CaCO 3 phosphor shows redemission, 3 and Dy 3þ doped phosphor shows yellow-emission and blue-emission. Both of Eu 3þ and Dy 3þ ions have good luminescence characteristics under UV excitation. 9-12 The red emission of Eu 3þ , 5 D 0 À 7 F 2 , and the yellow emission of Dy 3þ , 4 F 9 = 2 À 6 H 13 = 2 are corresponding to hypersensitive transitions, which can be strongly influenced by the surrounding environment. 13 These two ions have been co-doped as dopants for different host compounds to prepare phosphors, including Sr 2 CeO 4 , KCaBO 3 , etc. Considering the cost and the application of phosphor, calcium carbonate is the effective host of rare-earth ions, and has been widely used for stuffing of plastic or rubber, neutralizer, antacid, etc., therefore rare-earth ions doping calcium carbonate phosphors has the potential for applying to the plastic for anti-counterfeiting technologies.So far, there are few reports on CaCO 3 phosphors activated by Eu 3þ accompanied with Dy 3þ , therefore we undertake this work and present a new tunable and easily synthesized Eu 3þ -Dy 3þ co-doped CaCO 3 phosphors...
