摘要
Abstract This study explores the integration of X‐ray‐induced photochromism and photoluminescence in a single material, offering innovative multi‐mode applications in optical memory, anti‐counterfeiting, and X‐ray detection and imaging. The photochromic phosphor LiAlSi 2 O 6 :Sm 3+ is synthesized, which undergoes a color change from white to dark green under bright field conditions and displays orange photoluminescence in dark field conditions after X‐ray exposure due to defect formation. The phosphor shows accelerated bleaching and recovery under 473 nm laser stimulation. The distinct X‐ray‐induced color contrast and luminescence intensity modification in LiAlSi 2 O 6 :Sm 3+ highlight its potential in advanced luminescent material design. Moreover, a LiAlSi 2 O 6 :Sm 3+ ‐based flexible film demonstrates “dual‐mode” 3D X‐ray imaging and detection capabilities, paving the way for future X‐ray detecting and imaging device research.
