  The quaternary tungstates Li3Ba2RE3(WO4)8 (RE = La–Nd, Sm–Ho) were obtained by a ceramic synthesis route and were characterized by powder and single crystal X-ray diffraction. The structures of Li3Ba2Pr3(WO4)8 and Li3Ba2Tb3(WO4)8 were refined from single crystal diffractometer data: RbLiBi2(MoO4)4 type, space group C2/c, a = 528.57(2), b = 1292.39(6), c = 1934.80(10) pm, β = 91.522(4)°, 2151 F2 values

  A corrosion-inhibiting pigment comprising a rare earth element and a valence stabilizer combinded to form a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, terbium, praseodymium, or a combination thereof, and at least one rare earth element is in the tetravalent oxidation state. An inorganic or organic material is used to stabilize the tetravalent rare earth ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of tetravalent cerium, terbium, or praseodymium during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Many rare earth-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.

  一种缓蚀颜料，由稀土元素和价态稳定剂结合形成稀土/价态稳定剂复合物。稀土元素选自铈、铽、镨或它们的组合，至少有一种稀土元素处于四价氧化态。使用无机或有机材料来稳定四价稀土离子，以形成稀溶于水的化合物。选择特定的稳定剂是为了控制四价铈、铽或镨在遇水时的释放率，并调整粉末在所选粘合剂体系中用作颜料时的相容性。稳定剂还可以改变成型粉末的加工和处理特性。本文介绍了许多稀土-价稳定剂组合，其性能可与传统的六价铬体系媲美。

  A new technique to stabilize transition metal phosphors in a wide variety of stimuli-sensitive polymers and gels is disclosed herein. Other than stabilization in stimuli sensitive/biocompatible matrix some of these transition metal based phosphors are also shown to act as phosphorescent crosslinkers that physically or chemically crosslink polymeric chains to form micro/nanoparticles. The microspheres/nanospheres of the present invention show decreased size and photoluminescence enhancement with particularly high sensitization at physiological pH and temperature. The so formed phosphorescent micro/nanospheres are useful for biological or environmental applications including biological labeling, imaging, and optical sensing. The techniques in the present invention enable usage of imaging agents and sensors at very low concentrations and also minimize or eliminate the usage of toxic chemical crosslinkers typically used to synthesize polymeric micro/nanoparticles.
