Sentence examples for excited level from inspiring English sources

and long fluorescence lifetime (1.302 ms), owing to the favorable degree of energy matching between the triplet excited level of the ligand and the resonant level of Tb III) ions.

The decrease of EA with increasing annealing temperature indicates the narrowing of energy gap between the Er3+4I13/2 excited level and the trap states, and the decrease of WB is ascribed to the gradual passivation of non-radiative trap states during thermal treatments.

In the second case, an efficient energy transfer leads to the fact that the two ions can never be simultaneously excited to their first excited level (4I 13/2 energy level).

The easiest way to explain qualitatively (and to the large degree of precision, quantitatively) the negative value of the excited-state polarization at the small and moderate electric fields lies in the analysis of the first excited level for the pure Neumann BCs.

The spontaneous transition rate as an atom goes from an excited level to a lower one varies roughly as the cube of the frequency of the transition.

In fluorescence, an electron is raised from a certain baseline energy known as the ground level to an excited level by a light photon or other radiation.

Laser beam energy is not enough to excite electrons from energy levels near the top of valence band to Ce 3+ excited levels.

The Lu3+ ion has no excited 4f levels, and therefore, thermal quenching of Lu3+ 5d-4f luminescence cannot have been caused by nonradiative transitions to 4f levels and should be attributed to the thermally activated ionization of 5d electrons to the conduction band [21, 22].

The Lu3+ ion has no excited 4f levels; therefore, the peaks between 500 and 600 nm can be assigned to the ionization of Lu 5d orbitals and lattice of Sb2Se3.[22] 22], and the peak at 830 nm can be assigned to the 2F7/2→2F5/2 transition (f-f transitions) of the Yb3+ ions [23].

The paper reports and compares the results of the electromechanical, acoustical and thermodynamical characterization of a low-frequency sonotrode-type ultrasonic device inside a small sonoreactor, immersed in three different loading media, namely, water, juice and milk, excited at different excitation levels, both below and above the cavitation threshold.

The wave-fronts then are fast, directional, progressions of relative excitation from sites already excited over the level prevailing when only the gray screen is shown.
