Mechanoluminescence from Visible to Second Near‐Infrared Region Based on Sr3Sn2O7 Matrix

open access: yesAdvanced Optical Materials, EarlyView.
This study reports a defect‐tolerant derived layered perovskite Sr3Sn2O7: Ln3+ system exhibiting exceptional multimodal luminescence across 450–1600 nm. The material integrates photoluminescence (PL), persistent luminescence (PersL), X‐ray excited luminescence (XEL), and intense mechanoluminescence (ML) with 30‐fold higher ML intensity than PersL for ...
