Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

Advanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Medical & Biological Engineering & Computing, 1987
A number of new optical techniques for both thein vivo identification of blood analytes and the measurement of physical properties of interest to the clinician have recently been developed. These optical transducers are based on glass or plastic fibres, fractions of a millimetre (100–250 μm) in diameter, as found in fibre-optic communication systems ...

Optical fibre SERS sensors

Analytical and Bioanalytical Chemistry, 2009
Surface-enhanced Raman scattering (SERS) has established itself as an important analytical technique. However, efforts to transfer the technology from the laboratory to the production line, clinic or field have been frustrated by the lack of robust affordable substrates and the complexity of interfacing between sample and spectrometer.
