Their findings address one of the major challenges limiting the practical use of perovskites: their instability. These semiconductor materials could play an important role in next-generation optical technologies, but their tendency to degrade has long posed a challenge for researchers worldwide.","pubDate":"Wed, 21 Oct 2026 18:00:02 EDT","url":"https://phys.org/news/2026-10-perovskite-laser-stable-million-pulses.html"},"indexado":"2026-10-21T22:01:56.867Z"}}
