Elaboration and characterization of a KCl single crystal doped with Er3+

variations in the relative intensities of the two sets of satellite reflections for different crystals, (ii) the observation of single domains by electron.. diffraction [5

Even when we consider diffraction from a very small crystal, where the shapes of diffraction spots are only determined by the mosaicity distribution of the crystal, the

In this paper we are going to focus our attention on three features which are characteristic for this spectral range, namely the shift of oscillator strength away from the

They have shown that near threshold the absorption spectra show big differences between the gaseous and solid state ; for energies of 10 eV or more above threshold

As for Sc 2 O 3 , the orbital mixing of the 3d–t 2g orbitals of the neighbouring Sc atoms with the empty 4p states of the absorbing Sc atom via the 2p states of the O ligand results

growth (opcn circles). The values plotted for the optical bands were obtained by using the proper resolved gaussians. 3.4 RADIATIVE LIFETIMES. Discussion

ending at'ihe central photoabsorbing atom with n - l intermediate steps on the surrounding atoms, R P , indicates the corresponding total path length and the

The spectrum obtained with an excitation energy of 570 eV is very similar to the spectrum obtained by electron bombardment ( Fig. Figure 4b shows the h3 x-ray emission
