We investigate the effect of film morphology and phase segregation in polymer/colloidal PbS nanocrystal films on the near-infrared photoluminescence quantum efficiency (PLQE) of the nanocrystals. A direct correlation between the size of closed packed nanocrystal phase separated domains and lower PLQE was established. Films with a near-infrared PLQE of up to 12% have been prepared.
Several triply-bridged diruthenium(II) (1,4-bis(diphenylphosphino)butane) complexes were synthesised and characterised by elemental analysis, UV-Vis, NMR and IR spectroscopies. The solid-state structures of [(dppb)ClRu(μ-D 2 O) (μ-Cl) 2 RuCl(dppb)] (1), [(η 2 -H 2 )(dppb)Ru(μ-Cl) 3 RuCl(dppb)] (2) and [TMP][dppb)ClRu(μ-Cl) 3 RuCl(dppb)] (3) were established...
