In inorganic materials doped with rare earth ions, we have mainly two mechanisms for hole-burning; one is optical pumping to hyperfine sublevels in rare earth ions, and the other is optically induced rearrangement of local structure around optical centers. In crystals we often observe the hole due to the former mechanism while the hole due to the latter is reported mainly in glasses. Up to now, there seems to be only little study about the correlation between the mechanism of hole-burning and sample-quality or defects. Recently we reported that the character of holes in Y2O3:Pr3+ depends on the quality of samples [1]. In this paper we study the origin of these holes in Y2O3 with a well-controlled manner. For this purpose, we applied hole-burning spectroscopy to various Y2O3:Pr3+(0.2mol%) samples doped with other metallic ions.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121439165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such photoresponsive molecules as azobenzene and spiropyran derivatives have been proved to be effective guest molecules to bring about the photochemical phase transition. 1-5 The mechanism of the photochemical phase transition is interpreted in terms of the change in the molecular shape of the guest molecules by the photochemical reaction. For example, trans-azobenzenes are rod-like shape, stabilizing the LC phase, while cis-azobenzenes are bent, destabilizing the LC phase. When the trans-azobenzene/nematic (N) LC mixtures are irradiated to cause trans-cis photoisomerization of the guest molecules, the LC phase of the mixtures is destabilized in accumulation of the cis form and the N to isotropic (I) phase transition temperature (tNI) is lowered. When tNI is lowered below the irradiation temperature, N-I phase transition of the guest/host mixture is induced isothermally. This process is reversible, and cis-trans back isomerization restores the initial N phase. Time-resolved measurements by the use of a pulsed laser have revealed that the photochemical N-I phase transition takes place in the time region of 50 ~ 200 ms for the nematic hosts of low-molecular-weight (LMW) as well as polymeric LCs.6,7 Propagation of perturbation in the form of the trans-cis isomerization of the guest molecules may require a relatively long time in the LC systems.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123995997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elucidation of electron-phonon interaction, the nature of a zero-phonon line and spectral diffusion in PSHB have been studied intensively together with the research aiming at its possible applicability to ultra-high density optical storage. However, as for the PSHB materials, most of the works have been carried out with porphyrins, phthalocyanines, and quinizarin including their derivatives, several organic dyes, samarium and some other inorganic ions. The number of molecules reported to show hole formation so far is restricted compared to a wide variety of chemical structure of organic molecules. This would be because it is usually thought that for the hole formation the existence of a zero-phonon line in guest molecules for SHB should be accompanied by the occurrence of some photochemical reaction of the guest molecules. A well-known exception on this point is the so-called non-photochemical hole burning (NPHB) [4]. Recently triplet-triplet energy transfer of guest molecule to a host photo-reactive matrix has been reported to be a new family [5] of PSHB systems with new mechanism.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125091847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use a recently developed synthetic method for the synthesis of high quality nanometer size (1-10 nm) II-VI semiconductor crystallites with narrow size distributions (σ <5%), emphasizing CdSe.2 Optical characterization of their electronic structure using pump-probe techniques, luminescence, and DC Stark techniques reveals both molecular and bulk-like characteristics as well as properties which are unique to nanometer size crystallites. We observe a number of discrete electronic transitions, assign them as coming from the creation of delocalized \"particle-in-a-sphere\" states using the theory of Ref. 3, and study their dependence on crystallite diameter.4 The Stark experiments are also compatible with the absorbing states as delocalized symmetric states. We use time resolved fluoresence line narrowing spectroscopy to study the dynamics of electron-hole recombination. We observe significant changes in electron-LO phonon coupling with time, temperature, and crystallite size and suggest that the electron-hole pair dynamics following photoexcitation are dominated by surface effects which are especially important in the smaller crystallites where a large fraction of the atoms are \"surface\" atoms.5","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125964355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
