Exciton-to-dopant energy transfer (ET) dynamics of Mn:CsPbX3 quantum dots (QDs), which is dominated by diverse physical factors, requires more comprehensive understanding. Here, the concentration-dependent photon reabsorption effect on ET has been meticulously analyzed in colloidal Mn:CsPb(BrCl)3 QDs. The results indicate that photons emitted smaller QDs are absorbed larger QDs, effectively providing additional excitation light to latter. reabsorbed play a crucial role significantly enhancing process Additionally, QDs/Poly(methyl methacrylate)/Ag/SiO2 multilayer films were fabricated study influence surface plasmon (SP) dynamics. reveal resonant between excitons and SP via dipole interactions can regulate Mn2+ emission intensity controlling distance excitons. These findings provide insights into QD potential methods for their luminescence performance practical applications.

Photodiodes are an essential semiconductor device used in medical imaging, high-energy physics, and UV-visible sensors. Recent progress has renewed interest exploring alloys of traditional materials for detector fabrication. Alloying amorphous selenium (a-Se) with other can potentially improve performance responsivity quantum conversion efficiency (QCE) address some limitations stabilized a-Se. To increase the sensitivity transport properties, we explore multilayer devices vertical lateral architectures. We use different combinations a-Se selenium-tellurium (Se-Te) compare implementing each as light-absorbing layer, aiming to determine whether tailoring based on wavelength absorption depth could detector's performance. For devices, a thin (90 nm) layer paired thick (15 μm) Se-Te proved be most effective device, improving both response at long wavelengths overall QCE, 13-15% improvement over single-layer UV 2.5% red wavelengths. In combination layers outperformed single a-Se; however, solid gave highest QCE peak 30% 355 nm 15 V/μm. These findings demonstrate how structures affect performance, better guiding architecture end application, desired sensitivity, efficiency.
