Abstract

Ultrabroadband near-IR (NIR) emission has been realized in bismuth-embedded sodalite nanocrystals. Steady-state and time-resolved photoluminescence and Raman results suggest that Bi(+) active centers contribute to the NIR emission. This study demonstrates that sodalite nanocrystals can serve as excellent hosts for bismuth NIR active centers, thus paving the way for their wide applications in nanophotonics.

摘要

铋嵌入方钠石纳米晶体中实现了超宽带近红外（NIR）发射。稳态和时间分辨光致发光和拉曼结果表明，Bi(+)活性中心有助于 NIR 发射。本研究表明，方钠石纳米晶体可以作为铋 NIR 活性中心的优异宿主，从而为它们在纳米光子学中的广泛应用铺平了道路。
