"Published in SPIE Proceedings Vol. 9286", We present a flexible fluorescence lifetime imaging device which can be employed to scan large sample areas with a spatial resolution adjustable from many micrometers down to sub-micrometers and a temporal resolution of 20 picoseconds. Several different applications of the system will be presented including protein microarrays analysis, the scanning of historical samples, evaluation of solar cell surfaces and nanocrystalline organic crystals embedded in electrospun polymeric nanofibers. Energy transfer processes within semiconductor quantum dot superstructures as well as between dye probes and graphene layers were also investigated., This work was financially supported by the European Regional Development Fund (ERDF) through Programa Operacional Factores de Competitividade (COMPETE: FCOMP-01-0124-FEDER-014628) and the Portuguese Fundacao para a Ciencia e Tecnologia (FCT) through the projects "Functional structuring, inter-particle interaction and energy transfer in ensembles of nanocrystal dots" (PTDC/FIS/113199/2009), Ultra-fast spectroscopy on the dynamics and relaxation of Dirac electrons in graphene" (PTDC/FIS/101434/ 2008) and "Low dimensional nanostructures for nonlinear optical applications" PTDC/CTmNAN/114269/2009.
