Sentence examples for excited levels from inspiring English sources

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

Thus, the charge leaking effects on exciton emission from the ground and excited levels are similar, and the PL qualitative features are not expected to change substantially.

177Lu has a 100% probability of decaying via electron emission to three excited levels of 177Hf.

All β+ decay modes populate excited levels of 86Sr, with emission of cascades of prompt gammas.

Moreover, the dipole-allowed transition lifetime of the excited levels are applied to characterize the rotational distribution.

The singlet and triplet excited levels were calculated using the INDO/S-CIS method, implemented in ZINDO program.

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.

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 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].
