Abstract Persistent phosphor as a printing anti‐counterfeiting material has attracted strong attention owing to its inherent luminescent decay process and multi‐mode luminescence characteristics under external field stimulation. However, the dynamic persistent (PersL) pattern of single is only manifested in color changes still faces problem being easily decrypted. Herein, multi‐color with wide range distribution traps developed, which can emit white PersL. In addition, phosphors show an intelligent response thermo‐stimulated ambient temperature via recalling charging traps. The PersL mechanism proposed based on electron transfer between PbO 6 TbO octahedrons through O bridging. Based temperature, high‐throughput multi‐channel be achieved recording layer. This study not provides further insights into mechanism, but also opens new door for constructing responsive materials.

Mechanoluminescent materials have broad application prospects in advanced displays, stress imaging, and anti-counterfeiting owing to their ability convert mechanical stimuli into light. However, most previous studies focused on the visible near-infrared regions. Although natural ultraviolet C (UVC) light is nearly absent Earth's surface, it plays an important role many fields. Therefore, development of smart capable emitting UVC mechanoluminescence (ML) expanding scenarios ML are significant but challenging. Here property Sr

Persistent phosphor has emerged as a promising candidate for information storage due to rapid accessibility and low-energy requirements. However, the low capacity limited its practical application. Herein, we skillfully designed developed NaGdGeO4:Pb2+,Tb3+ stimulated by trace doped Sm3+. As expected, this demonstrates larger carrier than traditional commercial SrAl2O4:Eu2+,Dy3+ phosphors superstrong thermostimulated luminescence (TSL) that is three times greater photoluminescence (PL) intensity (PL efficiency, 17.3%). A mechanism of enhanced controllable TSL proposed based on electron-hole defect pair structure. We further present high-throughput optical data recording in five dimensions single fluorescent film layer. The findings described here provide not only universal approach constructing materials but also new paradigm future generation technology.

Abstract Optical information storage technology offers several advantages, including cost‐effectiveness, multidimensional storage, and rewritable capability. Consequently, it has become increasingly popular for optical media. Herein, a novel material Na 2 CaGe O 6 :Bi 3+ (NCGO:Bi ) is developed using non‐equivalent substitution strategy, which exhibits photochromic (PC) ultraviolet persistent luminescence (UV PersL) properties. NCGO:Bi demonstrates excellent white‐to‐brown PC performance under 254 nm light irradiation. The brown phosphor can be effectively bleached 425 or thermal stimulation, demonstrating reversibility over multiple cycles. Additionally, the displays UV PersL characteristics. representative sample NCGO:0.001Bi with duration time exceeding 10 h after excitation, peaking at 358 nm.
