With hydrophobic properties and ordered layered structures, mono-n-dodecyloxy-phosphinyl-cerium (terbium) (MDPCT) organic-inorganic hybrid materials were synthesized using cerium nitrate, terbium nitrate and mono-n-dodecyl phosphate (MDP) surfactant with three functions, hydrophobic group and phosphorus precursor, and characterized by XRD, SEM, TEM, FTIR and PLS. The results show that the solvent affects the interlayer spacing, crystallization and luminescent intensity of the prepared MDPCT materials. MDPCT prepared in water exhibits a more ordered layered structure and a higher degree of crystallinity, as well as stronger luminescent intensity than that prepared in ethanol. Based on the excellent solubility in organic solvents, this MDPCT hybrid luminescent material will be a promising candidate for potential biomedical applications in fluorescent imaging and analysis.

“…Peaks of Ce 3d, O 1s, C 1s, P 2p and Ce 4d can be identified for both of the two samples. Referring to the data collected in the literature, 12 the peak located at about 133 eV is the result of P 2p 3/2 , indicating that the phosphorus exists completely in the form of PO 4…”

“…13,16 It has been found that the morphologies, crystalline structure, and size of the rare-earth compounds greatly influence the luminescent properties. 12,17 Therefore, it is of great significance to develop CePO 4 materials with novel hierarchical structures. To the best of our knowledge, the fabrication of CePO 4 microspheres has not yet been reported.…”

Redox hydrothermal synthesis of cerium phosphate microspheres with different architectures

Uniform CePO 4 microspheres are first synthesized via a highly efficient redox hydrothermal (RHT) route using unconventional tetravalent Ce(SO 4 ) 2 $4H 2 O as the cerium source. Products obtained at 150 C for 2h are hexagonal crystalline CePO 4 microspheres with diameters ranging from 2 to 5 mm. By tuning the hydrothermal reaction time from 0 to 96 h, the morphologies of the obtained products undergo evolution from rodlike to spherelike and then to lamellar spherelike and lamellar star-shaped particles, accompanied by the phase transition from monoclinic Ce(H 2 O)(PO 4 ) 3/2 (H 3 O) 1/2 (H 2 O) 1/2 to pure hexagonal CePO 4 and then to mixed phases of hexagonal and monoclinic CePO 4 . A possible growth mechanism based on dissolution-recrystallization was proposed. The photoluminescence properties were investigated and these CePO 4 microspheres exhibit a narrower emission than that of CePO 4 nanoparticles. In addition, Ln 3+ (Ln ¼ Eu, Dy, and Tb) doped CePO 4 microspheres were also prepared, and their photoluminescent properties were studied.

“…Hydrothermal synthesis appears to be the most widespread technique in the literature. 20,[32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48] A wet chemical synthesis was applied by Wang and Gao to prepare short rhabdophane rare-earth phosphate nanorods at 100 C, 49 while Yang and co-workers investigated the effect of reaction temperature on nanowire length in water-ethanol medium. 50 A simple room temperature synthesis was developed by Di and coworkers for Tb-doped CePO 4 nanorods.…”

A simple, environmentally and economically benign, scalable synthesis was developed for the production of micrometer long hexagonal cerium phosphate nanowires, complex urchin-like nanostructures and their terbium-doped counterparts. It was proven that neither sophisticated equipment nor structure directing agents or pH adjustment or tedious procedures are necessary, because the precise regulation of precursor addition rate is sufficient to control the morphology of the product nanostructures. Nanowires and nanourchins can be obtained by the instantaneous vs. drop-wise addition of phosphoric acid to an aqueous cerium nitrate solution, respectively. Terbium doping is readily achieved by dissolving a calculated amount of terbium nitrate in the precursor solution. Spherulitic lanthanide phosphate nanostructure formation mechanisms offered in the literature were critically reviewed and assessed against our experimental findings obtained by studying the sonochemical disintegration of nanourchins. Terbium doping introduced green luminescence and slowed down the temperature induced hexagonal to monoclinic phase transition of cerium phosphate.
