Abstract
The invention relates to a method for producing nanoparticles of zinc sulfide activated by silver and chlorine in an ecological furnace. The nanomaterial prepared according to the present invention is characterised in that it consists of spherical particles of zinc sulfide material having a nanostructure, the concentration of silver nitrate being 0.4 mg/g of zinc sulfide, giving efficiency and a luminescent glow. The luminescent glow of the silver-activated zinc sulfide was 67% of the luminescent glow of standard zinc sulfide material. The zinc sulfide prepared according to the present invention was also used to build a 610A-model radon cell. The efficiency of the new cell was 70% in comparison with the efficiency of a standard cell built using standard zinc sulfide material. The material prepared according to the invention has an excellent linear response to alpha particles with an energy of 5.48 million electronvolts, allowing the prepared material to be used in alpha-particle detectors and the measurement of radon gas concentration.
