Luminescence of uranium(VI) after liquid-liquid extraction from HCl by Aliquat® 336 in $n$-dodecane:1-decanol by time-resolved laser-induced luminescence spectroscopy

ZnO thin fi lms deposited at MEA ratio of 1.0 show the highest UV emission while the minimum UV emission intensity is observed in thin films deposited at ratio of 0.5 and the

The curves are theo- retical ; some of them (broken lines) are associated with transitions which are zero in the simplified model (see the

Quand on considère que ces flammes sont observées à travers la flamme bleuâtre du bec hunsen, et que les couleurs sont de plus modifiées par les

In strong electric fields produced by charged dislocations, the electrons from impurity levels and capture centers tunnel into the conduction band ( the first stage of DL).

In a system where the host ion has a smaller size than the aliovalent impurity ion the ccv according to Dreyfus [2] will be predominantly in the near neighbour (nn)

At short delay times (Fig. Ib) a new luminescence band (LE) centred ar- ound 1.17 eV dominates the spectrum.. As the delay time increases further it becomes progressively
