      Abstract: The near-IR luminescence properties of   two Er(III)-containing coordination polymers, namely,   [Er(btc)(H(2)O)(5)center dot 3.5H(2)O](x) [(btc)(3-) =   1,3,5-benzenetricarboxylate] and [Er(2)(bdc)(3)-(H(2)O)(4)](x)   [(bdc)(2-) = 1,4-benzenedicarboxylate] were investigated with the   aim of testing their potential use as optical materials Because   both present relatively small quantum yields and short   excited-state lifetimes, factors Influencing their luminescent   properties were deciphered ill an effort to Improve their   luminescent properties Thus, three other families of compounds   were also investigated. (i) the two corresponding dehydrated   compounds with respective chemical formula [Er(btc)] and   [Er(2)(bdc)(3)](x) for evaluating the importance of O-H   vibrators, (ii) the heterodinuclear compounds   [Er(2-2x)Y(2x)(bdc)(3)(H(2)O)(4)](infinity) (x = 0.2, 0.5, 0.8   and 0.9) for estimating the role of intermetallic quenching and   (iii) the heterodinuclear compounds   [Er(2-2x)Yb(2x)(bdc)(3)(H(2)O)(4)](x) (x = 0.2 and 0.5) for   checking whether Yb(III)-sensitized up-conversion can be induced   or not ((C) Wiley-VCH Verlag GmbH & Co KGaA, 69451 Weinheim,   Germany, 2009)
