abstract = {We report on the first experimental and theoretical investigations of ultrafast intramolecular energy transfer for a novel class of highly luminescent materials – nanostructured organosilicon luminophores (NOLs). For this purpose we designed, synthesized and investigated a NOL, (POPOP)Si2(3Ph-EH)6, consisting of six p-terphenyl (3Ph) donor and 1,4-bis(5-phenyloxazol-2-yl)benzene (POPOP) acceptor luminophores – well-known laser dyes widely used in plastic scintillators as an activator and a spectral shifter, respectively. The NOL shows excellent optical properties – molar absorption coefficient up to 2.6 × 105 L mol−1 cm−1, photoluminescence quantum yield up to 96% and pseudo Stokes shift of 100 nm. Its intramolecular energy transfer efficiency determined from steady-state optical measurements was found to be 93%, while the excitation lifetime was less than 1 ns. For deeper understanding of the processes of intramolecular energy transfer within NOLs, ultrafast spectroscopy investigations of the NOL, model donor and acceptor luminophores were performed for the first time for this class of compounds. It was found that the time constant of the energy transfer from donor to acceptor luminophores within the NOL is τ1 = 105 fs, which is significantly faster than the vibrational relaxation within the donor (ca. 400 fs). Based on these findings, a kinetic scheme of the electronic excitation energy deactivation processes in the NOL was developed. The results obtained not only directly prove that the mechanism of energy transfer within the NOLs is based on Förster resonance energy transfer of the excitation energy from donor to acceptor luminophores, but also highlight the advantages of NOLs and NOL-based materials for future photonics applications – fast and efficient plastic scintillators, scintillating fibers and other spectral shifting optical materials.},

abstract = {Hybrid metal halide perovskites have shown an unprecedented rise as semiconductor building blocks for solar energy conversion and light-emitting applications. Currently, the field moves empirically towards more and more complex chemical compositions, including mixed halide quadruple cation compounds that allow optical properties to be tuned and show promise for better stability. Despite tremendous progress in the field, there is a need for better understanding of mechanisms of efficiency loss and instabilities to facilitate rational optimization of composition. Starting from the device level and then diving into nanoscale properties, we highlight how structural and compositional heterogeneities affect macroscopic optoelectronic characteristics. Furthermore, we provide an overview of some of the advanced spectroscopy and imaging methods that are used to probe disorder and non-uniformities. A unique feature of hybrid halide perovskite compounds is the propensity for these heterogeneities to evolve in space and time under relatively mild illumination and applied electric fields, such as those found within active devices. This introduces an additional challenge for characterization and calls for application of complimentary probes that can aid in correlating the properties of local disorder with macroscopic function, with the ultimate goal of rationally tailoring synthesis towards optimal structures and compositions.},
