Summary: This study proposes a bicomponent perovskite nanocomposite (BPNC) for color conversion layers in micro-light-emitting-diode (micro-LED) arrays, which significantly enhances the photoluminescence intensity through the built-in Forster resonance energy transfer (FRET) from the core CsPbBr3 to the shell gamma-CsPbI3. The FRET is conducted through a pair of combined quasi-degenerate energy levels in the blue spectra region, resulting in high excitation wavelength selectivity. The BPNC exhibits the brightest single-peak red photoluminescence with near 100% quantum yield and is adaptable to a wide range of emission wavelengths when used as color downconversion layers in a blue micro-LED array.

Summary: The time-resolved donor-detected Forster resonance energy transfer (trDDFRET) allows observation of molecular interactions within 10-100 angstrom region, while the time-resolved acceptor-detected FRET (trADFRET) can observe longer-range interactions. A new methodology based on trADFRET, namely FLIM-trADFRET, has been proposed to observe biological machinery in the range of 100-300 A in vivo. Proof of concept was demonstrated with a set of well-defined DNA scaffolds to evaluate this new methodology.

Summary: Metal-organic frameworks (MOFs) show potential in electromagnetic wave (EMW) absorption due to their tailored components, topological structure, and high porosity. In this study, rod-like conductive MOFs (cMOFs) composed of adjustable metal ions and ligands were prepared to achieve tunable dielectric properties for tailored EMW absorption. The influences of composition, charge transport, crystalline structure, and microstructure on dielectric and EMW absorption performance were investigated, advancing the understanding of EMW attenuation mechanisms. The cMOFs exhibited prominent EMW absorption due to enhanced conductive and polarization losses from conjugation effects, terminal groups, and shape anisotropy.
