Experimental lifetime determination in neutral praseodymium (Pr I) and neodymium (Nd I)
Radiative lifetime measurements have been performed, with a time-resolved laser-induced fluorescence technique, for 18 even-parity levels of Pr I and 15 odd-parity levels of Nd I. The new results are compared with the few experimental data available in the literature and good agreement is found. However, fragmentary knowledge of the spectra prevents reliable calculation of branching fractions a...
متن کاملPraseodymium(III) sulfate hydroxide, Pr(SO4)(OH)
The title compound, Pr(SO(4))(OH), obtained under hydro-thermal conditions, consists of Pr(III) ions coordinated by nine O atoms from six sulfate groups and three hydroxide anions. The bridging mode of the O atoms results in the formation of a three-dimensional framework, stabilized by two O-H⋯O hydrogen-bonding inter-actions.
متن کاملAtomic Layer Deposition of Praseodymium Aluminum Oxide for Electrical Applications
Praseodymium aluminum oxide (PAO) thin films were grown by atomic layer deposition (ALD) from a new precursor, tris(N,N′-diisopropylacetamidinato) praseodymium, (Pr(amd)3), trimethylaluminum (TMA), and water. Smooth, amorphous films having varying compositions of the general formula PrxAl2–xO3 were deposited on HF-last silicon and analyzed for physical and electrical characteristics. The films ...
متن کاملIndirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy
A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...
متن کاملLocalizing of a Four-Level Atom via Absorption Spectrum
We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. In the classical standing wave field, the interaction between the atom and the field is position dependent due to the Rabi-frequency of the driving field. Hence, as the absorption frequency of the probe field is mea...
