SYNTHESIS OF CALCIUM AND ALUMINUM OXIDES FROM SOLUTION OF PHOSPHATES ON LASER ABLATION OF POROUS SAMPLES

Abstract

The spectroscopic investigations of the surface laser plasma formed close to the porous body containing nanoquantities of different calcium and aluminum salts under the effect of two successive laser pulses were performed. The possibility for the development of methods to obtain the nanoclusters of metal oxides was demonstrated. Depending on the concentration of the starting metals in the solutions used, one can vary both the quantity and composition of the metal oxide clusters.
