Dielectric and infrared properties of srTiO_3 single crystal doped by 3d (V,Mn,Fe,Ni) and 4f (Nd,sm,Er) ions

引用

Chinese Physics B 2014年第2期23卷 369-374页

作者： s.Maletic D.Maletic I.Petronijevic J.Dojcilovic D.M.popovic Faculty of Physics University of Belgrade Institute of Physics University of Belgrade

In this study, the effects of doping by 3d （V, Mn, Fe, Ni） and 4f （Nd, sm, Er） ions on dielectric and infrared properties of srTiO3 （sTO） single crystals are investigated. It is well known that doping of the srTiO3 can change the dielectric properties of the sTO from an insulator to an n-type semiconductor, and even to a metallic conductor. Dielectric and infrared （IR） properties of the undoped sTO and doped sTO single crystals are analyzed using dielectric spectroscopy （80 kHz-5 MHz）, transmission （200 cm^-1-4000 cm^-1）, and reflection spectroscopy （50 cm^-1-2000 cm^-1）. It is found that doping by the 3d ions reduces the value of dielectric permittivity, but the trend of temperature dependence of the dielectric permittivity remains almost unchanged. On the other hand, dielectric spectroscopy measurements for samples doped by 4f ions show the anomalous behaviors of the dielectric permittivity at temperatures around the temperature of the structural phase transition. There are two fractures of temperature dependences of inverse dielectric permittivity εr^-1 （T）. Transmittance spectroscopy measurements show that there are differences in the shape of the spectrum in the mid-IR region between the undoped sTO and the one doped by 4f ions. The differences in the reflectance spectrum between the sTO：Nd and sTO are analyzed in detail.

Response of Growth Dynamics of Two spring Geophytes to Light Regime in a Lime-Beech Forest

引用

Journal of Integrative Plant Biology 2006年第5期48卷 527-535页

作者： Zorica popovic Aleksandar Mijovic Branko Karadzic Miroslava Mijatovic Institute of Biological Research Department of Ecology Despota Stefana Boulevard 142 11060 Belgrade Serbia and Montenegro Environment Protection Agency Ministry for Science and Environmental Protection Republic of Serbia Serbia and Montenegro

Blomaee accumulation, leaf longevity and growth rate of two spring forest geophytes, scllla blfolla L. and Arum maculatum L. were estimated separately for three size groups within each population of these species. Despite the differences in leaf longevity, both species showed a similar pattern of blomass accumulation In relation to their phenologles and reproductive demands. Eco-physlological acclimation to changing light environment was assumed through photosynthetic parameters and dynamics of leaf area Index In the predominant size group of each species. A light response curve was measured under natural light for each species through the continuum of Its phenology to quantify the photosynthetic photon flux density at light saturation, light-saturated photosynthetic rate, light compensation point, and dark respiration. Light-saturated assimilation per leaf area basis, dark respiration rate and light compensation points were significantly higher in s. blfolla relative to A. maculatum. However, the acclimation of photosynthesis that would respond to light changes in environment was not found in s. bifolla. In contrast, In A. maculatum a marked shift In the light dependence of photosynthesis through the season was noticed, which resulted In a strong photosynthetic acclimation to the low-light conditions. Accompanied by significant leaf area Index, this efficient low-light photosynthesis enabled greater leaf longevity, and consequently longer accumulative period to A. maculatum. From the different parameters that we determined （both photosynthetic acclimation and growth strategy） it would appear that these species belong to two distinct subgroups： s. blfolla to the early and A. maculatum to the late vernals.

Pyrite Formation in Organic-rich Clay, Calcitic and Coal-Forming Environments

Acta Geologica sinica(English Edition) 2006年第4期80卷 574-588页

The early diagenetic characteristics of pyrite formation processes in a Miocene freshwater sequence of mixed sediments （coal fragments in clays, sandstones or shales） alternating with continuous brown coal layers was investigated. Based on abundant minerals, the following main sedimentary environments were distinguished： the illite-montmorillonitic （I-M）, calcitic （Ct） and coal-forming environment （CL）. For these hydrogeochemically differing environments the effects of limiting factors on the pyrite formation process （availability of sulphate and Fe, amount of organic matter and participation of organic sulphur） were assessed by correlation analysis. significant differences in the effects of these limiting factors in the particular environments were observed. These differences were explained taking in account the different oxidative activity, Fe-complex and surface complex forming properties of humic substances in dependence of pH of environment and the abundance of sorptionally active clay minerals. In environments having a relatively low pH and containing clay minerals （I-M- and CL-environments） the oxidative activity of humic substances （Hs） on pyrite precursors was greatly prevented however pyrite formation depended on reactive Fe availability as the consequence of complex formation. On the contrary, in environments with a relatively high pH, as it was the calcitic, the oxidative activity of Hs was greatly enhanced, thus oxidizing the sulfur precursors of pyrite. The oxidation degree of organic matter was probably also a consequence of the differing activity of the humic electron-acceptors.
