The study of abnormal Wilson transitions from metal to nonmetal states in simple electronic systems under high pressure plays an important role understanding the profound physical mechanisms associated with structures materials. Moreover, such studies serve as references for complex systems. Of particular interest is that Li-O have been demonstrated exhibit both normal and transition behaviors at depending on Li O ratio, compounds also superconductivity. However, pressure-induced phase...
We study the steady-state and time-resolved luminescent properties of CdTe nanocrystals by one- two-photon excitation with a femtosecond laser. observe that 1208 nm causes shift emission peak about 20 to infrared compared 400 laser excitation. It is found upconversion luminescence composed photoinduced trapping band edge excitonic state produces observation biexponential decay kinetics. conclude redshift caused relative change in intensity between states.
Abstract Using microwave plasma torch (MPT) as an excitation light source, argon support gas, the sample solution was introduced into by pneumatic nebulization system. The determination of silicon, iron, and vanadium in petroleum coke atomic emission spectrometry (MPT-AES) studied. experimental conditions were optimized chosen. effects coexistent ions on signal investigated detail. detection limits for 0.040 μg/mL, 0.022 0.052 respectively. Linear dynamic ranges 0.2–6 0.1–100 0.2–100...
Abstract A study of the fluorescence system Eu3+-2-benzoyl-indan-1,3-dione-trioctylphosphine oxide-Triton X-100 was made. The excitation and emission wavelengths were 348 612 nm, respectively. intensity a linear function concentration europium in range 1.0×10−8 - 1.0×10−6 mol/L. detection limit 4.0×10−9 standard addition method used for determination rare earth oxides, with satisfactory results.
