Abstract
A principal possibility of formation the nanostructures on the surfaces of 50РЬО-25Вi 2 O з −20Са 2 O з − 5BaO (doped by Eu 3+ , Er 3+ , Dy 3+ ) is demonstrated by using multi-coherent beams. As a sources of the photoinducing coherent light we have used nanosecond Nd:YAG and Er:Yb lasers generating at 1064 nm and 1540 nm, respectively. The morphology of the photoinduced surfaces is sensitive to the type of rare earth ions. The thickness of the layer was about 20‖30 nm. Possible mechanisms are explained by coherent photoinduction of the valence electrons.
