BaO-B_2O_3-BaBr_2∶Eu^(2+)体系磷光体的合成、结构及发光

本文研究了BaO-B_2O_3-BaBr_2:Eu^(2+)系列发光材料的制备方法、组成、结构及其发光性能。最佳配比为Ba_2B_5O_9Br:Eu^(2+),这是一种很有应用潜力的X射线增感屏发光材料。

Synthesis and Characterization of Water－Soluble Mono（tetrapyridylporphyrinato）Gadolinium（Ⅲ）［Gd（tpyp）OH·DMSO·23H_2O］

A reaction of tris(acetylacetonato) gadolinium (Ⅲ), [Gd(acac)3], with tetrapyridylporphyrinato dilithium,Li2tpyp,produces a water-soluble complex mono(tetrapyridylporphyrinato) gadolinium (Ⅲ).[Gd(tpyp)OH·DMSO·23H2O], in appreciable yield. Another water-soluble complex,mono(tetramethylpyridylporphyrinato) gadolinium (Ⅲ) is formed by methylation of the tpyp ligand in [Gd(tpyp)OH·DMSO·23H2O]. Their monomariac constitution is proved by UV-vis. I R, mass spectra and elemental analysis.
