TL;DR: In this article, the luminescence properties of divalent europium complexes with crown ether, azacrown ether, N-pivot-azacrown- ether, and cryptand in methanol or water have been systematically investigated under UV irradiation.

TL;DR: In this paper, the chemical vapor transport (CVT) efficiency for pure yttrium chloride YCl 3 mediated via RAl n Cl 3+3 n vapor complex was measured and compared with those of lanthanoid chloride LnCl 3 (Ln=Dy, Ho, Er), in which these four kinds of rare earth ion R(III), especially Ho, Y and Er, have very similar ionic radius values.

TL;DR: In this paper, the progress in the field of mutual separation of rare earths from the rare earth ores and their recovery from rare earth containing industrial waste by the dry chemical vapour transport (CVT) process mediated by the corresponding gaseous rare earth complexes with aluminum or alkali chlorides, RAI n Cl 3+3 n or KRCl 4, is reviewed and discussed on the basis of their thermodynamic characteristics.

TL;DR: In this article, a reaction of tris(acetylacetonato) cerium(III), [Ce(acac)3], with tetrapyridylporphyrinato dilithium, Li2tpyp, produces a water-soluble sandwich complex bis(tetramethylpyridynylporphyrinato) cerium(IV), in appreciable yield.

TL;DR: In this article, the mutual separation characteristics of rare earths Sc, Y and La from the binary systems R 2 O 3 -R 2 O O 3 (R: rare earth, Y, La) by the chemical vapour transport (CVT) process mediated via RAl n Cl 3+3 n or RKCl 4 vapour complex under various different slopes of temperature gradient were investigated.
