Nanosize Tin ‘Bubbles’ Could Provide Low-Cost Way to Generate EUV Light

Scientists at Tokyo Institute of Technology (Tokyo Tech) have generated low-cost extreme ultraviolet (EUV) light by creating tin thin-film spheres using a polymer electrolyte “soap bubble” as a template and irradiating it with a laser. When the spheres were irradiated, the scientists were able to confirm the emission of EUV rays of 13.5 nm, which is the same as metallic tin. The low-density tin “bubble” could provide a reliable way to generate EUV light for use in electronics, biotechnology, and cancer therapy. High-intensity lasers have been used to generate EUV light, but it has been challenging for these lasers to maintain control of a target density that can produce light in the EUV range. Tin has been...
