A spectral-kinetic recorder operating in a special time-gating mode was developed for time-shifted measurement of time-resolved spectra and emission-line intensity kinetics in atomic emission analysis. The luminescence intensity kinetics of Cu, Zn, Sn, and Pb were recorded for two-pulse laser ablation of pure metals and multicomponent alloys. The spectral-line intensity kinetics of pure metals cou...... hiện toàn bộ

Luminescence of lead sulfide (PbS) nanocrystals with mean diameter 6 nm in a silicate glass matrix that emit in wavelength region 1.5 μm (0.827 eV) is studied. The average luminescence decay time is estimated to be 2.7 μs. Decreasing the temperature is shown to result in a shift of the emission spectrum to lower energies with a corresponding temperature coefficient of 64 μeV/K. Anti-Stokes lumines...... hiện toàn bộ
