Perovskite quantum dots (QDs) are high-efficiency optoelectronic materials attracting great interest, but further improvement in the luminescence efficiency is crucial for their application. In this work, we enhance both spontaneous emission rate and photoluminescence (PL) intensity of CsPbBr3 QDs by coupling them to a high quality (Q) factor SiO2 microdisk cavity. Compared conventional metal plasmonic cavities, dielectric cavity structure suppresses effects quenching energy transfer, which could introduce complex fluctuations nonradiative decays. As such, obtain 5.9-fold enhancement PL 5.6-fold rate. Moreover, different behaviors phonon sidebands allow us explore components broad peak ensembled QDs. These results demonstrate potential cavities enhancing devices exploring exciton-photophysics perovskite

The global burden of colorectal cancer is significant and the limitations conventional treatments like radiotherapy chemotherapy require novel approaches to manage neoplasia. This review explores theranostic integration quantum dots plasmonic nanoparticles its potential in overcoming challenges diagnosing treating Quantum (QDs) facilitate fluorescence imaging targeted delivery, enabling precise detection localized therapy because QD's unique optoelectronic properties. Furthermore, their improve cell destruction while protecting normal tissue can be observed utilization photodynamic therapy. Plasmonic are a non-invasive approach tumour ablation which induces photothermal effect by leveraging surface plasmon resonance. A platform that incorporates QDs provide simultaneous treatment capabilities, facilitating real-time monitoring response improved therapeutic outcomes with minimized side effects. However, have several related nanoparticle design, biocompatibility lack clinical translation. By these challenges, full realized. highlights opportunities for further study development underscoring promising role transforming

The use of nanostructures to enhance the emission single-photon sources has attracted some attention in last decade due development quantum technologies. In particular, metallic and high-refractive-index dielectric materials been proposed. However, utility moderate-refractive-index achieve more efficient remains unexplored. Here, a systematic comparison various metallic, was performed optimize excitation CdSe/ZnS single dot visible spectral region. Several geometries were evaluated terms electric field enhancement Purcell factor, considering combination conforming homogeneous hybrid nanoparticle dimers. Our results demonstrate that nanoparticles can photoluminescence signal emitters their broader magnetic dipolar resonances compared nanoparticles. combinations offer largest intensity factors at wavelengths emitter, respectively. this work may find applications sources.
