This paper investigates the photo-excited electron and hole polaron dynamics in cerium dioxide (CeO₂) using time-resolved X-ray absorption spectroscopy, with an emphasis on the nano-size effect. Additionally, density functional theory and multiplet calculations have been utilized to reveal the photo-excited polaron dynamics in CeO₂ single crystal (SC) and nanocrystal (NC). The electron polaron is observed to decay into a deep trap site with a short duration of ≈5 ps, while electrons in the traps stay for more than 1400 ps. The most significant observation is the behavior of holes in NC, which tends to stay longer (≈150 ps) compared to SC (&lt;10 ps) suggesting hole existence more at the surface than at bulk. The fast dissociation of the electron polarons the prolonged lifetime of the electrons above the Fermi level and the enhanced hole lifetime at the surface are proposed to be among the various factors that influence the high reactivity of CeO₂.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 1","pages":""},"PeriodicalIF":9.0,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the probing polarization dependence of non-equilibrium dynamics in NbIrTe₄ is investigated by using transient reflectivity spectroscopy. Following photoexcitation at 3.18 eV, the dynamical response of 1.59 eV probe pulse exhibits a strong dependence on probe polarization. The relaxation comprises two components: a rapid recovery of ≈0.6 ps attributed to the electron–phonon scattering, and an anomalous slow recovery spanning hundreds of picoseconds attributed to the photoinduced quasi-particle. The polarization dependence of rapid relaxation time τ is indicative of the in-plane anisotropy of electron–phonon coupling in NbIrTe₄. The slow relaxation modulated by a latest reported 16 cm⁻¹ coherent phonon also shows strong probing polarization dependence, further revealing the anisotropic nature of electron–phonon coupling and the possibility of anisotropic lattice distortion, as well as photoinduced polaron, under ultrafast photoexcitation in NbIrTe₄. The dynamical anisotropy in NbIrTe₄ has provided valuable guidance for the application of NbIrTe₄ in polarization-sensitive nonlinear optics or optoelectronic devices and offers insights into the unique carrier transport as well as phonon transport properties of this newly established topological material.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"53 1","pages":""},"PeriodicalIF":9.0,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, in order to optimize the birefringence, the methyl modulation of π-conjugated organic planar units is proposed and implemented with the urea structure as a template. Thus, <i>N</i>-methylurea and <i>N,N'</i>-dimethylurea crystals are obtained by partially replacing hydrogen atoms with methyl groups. This replacement reduces hydrogen donors and weakens interchain hydrogen bonds, which facilitates the decreasing density and the parallel arrangement of π-conjugated planar units. Hence, both <i>N</i>-methylurea and <i>N,N'</i>-dimethylurea crystals exhibit not only an optimized birefringence (<i>N</i>-methylurea ≈0.099 and <i>N,N'</i>-dimethylurea ≈0.072 at 546 nm) but also an enhanced SHG response (<i>N</i>-methylurea ≈1.2 × <i>β</i>-BaB₂O₄ and <i>N,N'</i>-dimethylurea ≈1.9 × <i>β</i>-BaB₂O₄), while maintaining a short UV absorption cutoff edge.
