Experimental results showed that energetic ion induced phase change in a solid could be achieved not only by irradiation at high fluences but also by singe ion induced huge electronic excitations. The phase change produced in the later condition is just along individual ion latent tracks。Poecently, we have proposed a novel technique,“low energy ion implantation + swift heavy ion irradiation”, for synthesizing new structures in atom mixed materials in which more attention was paid to the dense electronic excitations effect induced by theincident ions. In the present work, the technique[2} was used to investigate huge electronic excitations induced
