“…Based on the plasmons’ and excitons’ interaction and coupling strength, they can be classified into weak, intermediate, and strong coupling regimes. In the weak coupling regime, the plasmon frequency of metal nanostructure and excitons of optical emitters are coupled to increase their spontaneous emission rate (Purcell effect) 28 – 30 . Hence, a single emission peak with enhanced intensity is observed in the weak coupling regime.…”

The formation of plasmon-exciton (plexciton) polariton is a direct consequence of strong light-matter interaction, and it happens in a semiconductor–metal hybrid system. Here the formation of plasmon-exciton polaritons was observed from an AgTe/CdTe Quantum Dot (QD) solid system in the strong coupling regime. The strong coupling was achieved by increasing the oscillator strength of the excitons by forming coupled QD solids. The anti-crossing-like behaviour indicates the strong coupling between plasmonic and excitons state in AgTe/CdTe QD solids, resulting in a maximum Rabi splitting value of 225 meV at room temperature. The formation of this hybrid state of matter and its dynamics were studied through absorption, photoluminescence, and femtosecond transient studies.

“…[ 29 ] The 2.1‐fold PL enhancement at 1.28 μm was observed from the InGaAs/GaAs QDs embedded in a PhC waveguide. [ 30 ] The PhC composed of the InGaN/AlGaN core–shell dot‐in‐(GaN) nanowire array exhibited a stable PL at 505 nm arising from the embedded QDs. [ 31 ] The aggregation‐induced emission luminogens incorporated in the PhCs showed visible fluorescence having surrounding medium‐dependent wavelength.…”

People know little about the characteristics of the photonic crystals (PhCs) made of nanoscale building blocks, which can be quite distinct from the usual PhCs made of microscale or even larger units, because the unit size strongly affects the photonic structure. The PhCs made of fluorescent CuInSe2 quantum dots (QDs) having an ultrasmall average size of 2.2–5.3 nm are studied. The experiments and hybrid density‐functional theory calculation reveal that these QDs have defect‐related fluorescence, and the light absorption exhibits an unexpected indirect‐gap feature because of the discrete and small density of states at the direct‐gap maximum. The frequency‐domain electromagnetic calculations reveal that the PhCs made of the CuInSe2 QDs have a remarkable out‐of‐plane bandgap in the extreme‐UV (EUV) region. The frequency modes below and above the forbidden gap are separately air band and dielectric band modes. These multifunctional fluorescent semiconductor QD PhCs have application potential in nanoscale photonic devices and EUV photolithography.
