Chemical reactivity from the vibrational ground-state level. The role of the tunneling path in the tautomerization of urea and derivatives

Recent developments of low-temperature techniques are providing valuable knowledge about chemical processes that manifest in the quantum regimen.

Наблюдение когерентного пленения населенности в ансамблях NV-центров в алмазе в условиях антипересечения уровней основного состояния

We realize the coherent population trapping effect in ensembles of diamond NV-centers in the ground state level anticrossing regime when the sample is placed into a strong external magnetic field along the [111] crystal axis.

Visible Luminescence of Eu3+ Ions in Lithium Barium Borate Glass

Europium doped lithium barium borate glasses were fabricated by conventional melt-quench method and were analyzed their physical, optical and luminescence properties through absorption, excitation, emission and decay analysis at room temperature. The experimental data revealed that the five discrete absorption bands peaking at 393, 464, 532, 2032 and 2212 nm due to the transitions from 7F0 ground state level to various excited states of Eu3+ ions. The luminescence of Eu3+ in visible bands were observed under 394 nm pumping.
