SYNTHESIS OF CALCIUM OXIDE NANOCLUSTERS FROM THE SALTS INTRODUCED INTO PORIOUS BODIES ON LASER - CHEMICAL ACTIVATION OF THE PROCESSES

Abstract

The formation dynamics of calcium ions was studied under the effect of double laser pulses on the surface and bulk of porous bodies with solutions of Ca salts (CaCl2, Ca(NO3)2, CaCo3, and Ca3(PO4)2) in the air at the laser pulse energies 50-60 mJ and interpulse times 0-12 μs. It was found that the intensities of Ca II line (λ =393.367 nm) for the indicated salts form the following series: phosphate> carbonate>nitrate≥ chloride.
