AB  - A series of lanthanide-based coordination polymers 
      [Yb1-xErx(4,4'-bpdo)3(H2O)2](CF3SO3)3infinity were synthesised by solvent diffusion 
      techniques, where 4,4'-bpdo = 4,4'-bipyridine-N,N'-dioxide, and using differing 
      mole fractions of Yb(iii) and Er(iii) which were systematically varied (x = 0, 
      0.05, 0.20, 0.50 and 1). All of the materials obtained were characterised using 
      elemental analyses, single-crystal X-ray diffraction (SXRD) and solid-state 
      photoluminescence studies. Structurally, the coordination polymers crystallise as 
      an isomorphous series of infinite 2D sheets, which contain two inner sphere water 
      molecules, and are isostructural with a previously characterised homometallic 
      Yb(iii) compound. In addition to the normal Near Infra-Red (NIR) luminescence, 
      these compounds also demonstrate upconversion emission upon 980 nm excitation. 
      Upconversion luminescence measurements reveal visible emission in the red, green, 
      and blue regions corresponding to the (2)H11/2-->(4)I15/2, (4)F9/2-->(4)I15/2 and 
      (2)H9/2-->(4)I15/2 transitions of the Er(iii) cation upon two and three-photon 
      excitation. We also observed weak emission from the Er(iii) cation in the UV 
      region for the first time in a Ln-MOF based material.
