| Rezumat | ||||||
MgO crystals indented by the Vickers hardness indenter
have been studied by cathodoluminescence and
spectroscopic methods using a scanning electron
microscope. After annealing in the aluminum vapor or
melt at 1420 K for 150 h, changes in the mechanical,
optical and luminescence properties of the crystals
were observed. The changes were observed in both the
region of the indent rosette and non-indented region in
which Al diffusion occurred. An increase in the
microhardness and changes in the luminescence
properties were suggested to be related first of all to
the presence of aluminum impurities in the MgO
crystals. |
