Wolframa Dislenid is a semiconductor material similar to graphene in terms of properties. It has interesting optical and electronic properties. However, the layered structure complicates the creation of nanoparticles of the necessary shape. It was possible to solve this problem thanks to the combination of water and ultra -cesim laser impulses.
During the experiments, the researchers placed the crystals of Tungsten dyschidine in deionized water and processed with strong laser impulses of a second to a fraction of less than trillion. As a result, global nanoparticles occurred in a diameter of 10 to 150 nanometers.
While these particles maintain the properties of the starting material, they heat more effectively under the influence of light. They show four times higher activity than the original crystal and similar silicone nanoyaps. This makes it promising for use in the therapy in which the light is converted to heat – for example, in the treatment or diagnosis of tumors.
