The influence on luminescence is primarily elucidated through an analysis of geometry, electronic structure, and the dynamic processes occurring within the excited state. Structural analysis indicates that P35M exhibits the most effective luminescence due to minimal structural changes, reduced separation between the electron and hole, and enhanced intermolecular interactions within the crystal. Excited state dynamics and recombination energy analysis indicate that the higher triplet exciton population in the P35M molecule contributes to its long-lived phosphorescence. Furthermore, the intersystem crossing process for the three molecules is predominantly governed by low-frequency torsional rotation, while bond stretching vibrations are the primary factor leading to the inactivation of non-radiative processes. The distinct vibrational channels associated with reverse intersystem crossing and non-radiative processes present opportunities for further enhancement of the phosphorescent characteristics of these molecules.</p>","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single-layer structures face limited degrees of freedom, and cannot satisfy the growing functional demands for meta-devices. To simplify the design process and gain more controllability, quasi-2D structures are introduced into metasurfaces in the form of stacked meta-atoms design or spatially cascaded metasurfaces. These configurations greatly expand the manipulation capability of metasurfaces and spawn a variety of functions and applications. In this review, the progress of metasurfaces with multi-layer stacked meta-atoms and spatially cascaded metasurfaces is presented. Progress is presented from metasurfaces with multi-layer stacked meta-atom configurations to spatially cascaded metasurfaces, focusing on the development of versatile applications for these quasi-2D configurations. Special attentions are paid to the diffractive deep neural networks(D<sup>2</sup>NNs), and a category of recently developed cascaded metasurfaces introduces a brand-new method into metasurface inverse designing as well as paves paths to all-optical computing.

They generalize the Horndeski and beyond-Horndeski theories. Originally proposed to describe the late-time acceleration of the expansion of the universe, generalizing the cosmological constant, they can also be used to build models of the early universe, to describe inflation or alternatives to standard inflation. In the late universe, they modify the standard Vainstein screening mechanism from Horndeski theories (which can have observable consequences) and are suited to build black hole models, featuring non-stealth Kerr black hole solutions.

The order parameters, used to date, are not promising for computer detection of these types of structures. In this previous study, it is shown that machine-learning analysis using convolutional neural networks is very effective for the structural formation of spherical colloidal particles. This method is applied to non-spherical inverse patchy colloids and demonstrated that this order-parameter-free analysis method is effective for non-spherical soft matter, which often exhibits complex structures. A recent development in the structural formation of colloidal particle systems corresponds to the problem of monolayers of core-corona particle systems that exhibit a variety of structures. Monte Carlo simulations are performed for core-corona particles, confined between parallel plates, to clarify the conditions for the appearance of the bilayer and its in-plane structure formation.
