Light–matter coupling-induced hybrid states provide the potential to tune emission dynamics of molecular chromophores having multilevel systems. We demonstrate alteration delayed fluorescence by formation through interaction light with a thermally activated molecule embedded in conventional Fabry–Pérot cavity. The proximity cavity resonance excited state absorption is modified manipulating incident angles (with sample) instead varying active layer thickness. are observed angle-dependent...
Thermally activated delayed fluorescence (TADF) systems exhibit high emissive yield due to efficient back-conversion of nonemissive triplet states singlet via reverse intersystem crossing (RISC). In this paper, both the charge carrier and exciton dynamics are explored using transient electroluminescence (TrEL) measurements in TADF molecule, 2,3,4,6-Tetra(9H-carbazol-9-yl)-5-fluorobenzonitrile (4CzFCN)-based devices. The analysis rising edge TrEL pulse indicates that carriers follow multiple...
Abstract Triplet state modification in organic phosphorescence molecules for a desired color and quantum yield is typically pursued by chemical modification. A facile methodology introduced to tune the triplet dynamics of phosphorescent molecule changing host‐matrix parameters. An phosphor, Br 2 PmDI (2–Bromo pyromellitic diimide), dispersed at dilute levels (1.5 wt.%) semicrystalline high‐ κ relaxer ferroelectric host matrix emit room‐temperature accompanied delayed fluorescence component....
Abstract Patterned piezoelectric polymer films serve as a suitable template for exploring various applications based on the characteristic electrical and optical properties. Here, large‐area spontaneous pattern formation in relaxor terpolymer, poly(vinylidene difluoride‐trifluoroethylene‐chlorofluoroethelene) (P(VDF‐TrFE‐CFE)) films, is demonstrated using cost‐effective breath‐figure technique. The experimental parameters allowed controlling hemispheroidal patterns, with pore dimensions...
Color centers in nanodiamonds (NDs) have been largely explored by coupling to a photonic structured matrix (PSM) amplify visible range emission features, enhancing their use quantum technologies. Here, we study the enhancement of dual near-infrared zero phonon line (ZPL) from silicon-boron (SiB) and silicon-vacancy (SiV
