“…Afterglow materials show promising applications in diverse fields, such as biological imaging, anti-counterfeiting, and data encryption, due to their long-lived excited states. [1][2][3][4] As the emission lifetime of afterglow materials is longer than 0.1 s, their emission signals can be recorded by low-cost optical equipment. 2,[4][5][6][7] Even human naked eyes and phone cameras could record and distinguish the color, intensities, and durations of afterglow.…”

“…5,8 Currently, most of the commercial afterglow materials are inorganic structures doped with metal ions or organometallic systems, which are heavily dependent on rare earth or noble metals. 3,[9][10][11] To address this issue, pure organic materials were also developed into afterglow materials through modulating their room temperature phosphorescence (RTP), which needs precise molecular designs and elegant understanding of the relevant photophysical process. 1,7,12,13 Unfortunately, achieving efficient and long-lived RTP or afterglow is hindered by the spin-forbidden nature of triplet exciton transition, the rapid non-radiative decay of the triplet excitons, and proneness to quenching by oxygen and solvents.…”

“…[5,6] Among them, materials with activators doped in different oxide hosts (aluminates, silicates, stannate, etc.) [7][8][9] exhibit excellent LPL performance, and the corresponding spectral range covers ultraviolet (UV), visible, and even near-infrared light. [10][11][12] But the high latticeformation energy (≈3000 kJ mol −1 ) of such materials results in the requirement of high synthesis temperature for phase generation, [13] leading to an increase in manufacturing costs and safety risks.…”

Application of long‐persistent luminescence (LPL) materials in many technological fields is in the spotlight. However, the exploration of undoped persistent luminescent materials with high emission efficiency, robust stability, and long persistent duration remains challenging. Here, inorganic cesium cadmium chlorine (CsCdCl3) is developed, featuring remarkable LPL characteristics at room temperature, which is synthesized by a facile hydrothermal method. Excited by ultraviolet light, the CsCdCl3 crystals exhibit an intense yellow emission with a large photoluminescence quantum yield of ≈90%. Different from the reported systems with lanthanides or transition metals doping, the CsCdCl3 crystals without dopants perform yellow LPL with a long duration of 6000 s. Joint experiment‐theory characterizations reveal the intrinsic point defects of CsCdCl3 act as the trap centers of excited electrons and the carrier de‐trapping process from such trap sites to localized emission centers contributes to the LPL. Encouraged by the attractive fluorescence and persistent luminescence as well as good stability of CsCdCl3 against environment oxygen/moisture (75%), heat (100 °C for 10 h), and ultraviolet light irradiation, an effective dual‐mode information storage‐reading application is demonstrated. The results open up a new frontier for exploring LPL materials without dopants and provide an opportunity for advanced information storage compatible for practical applications.

“…Lanthanide complexes have a great attention of chemists over the past few years as a result of their diverse applications and function in biological systems, lightemitting instruments, and solid-state lighting devices. [1][2][3][4] There is always an urgent need to investigate new compounds that have the property of eliminating cancer cells. Lanthanide complexes showed antitumor activity, 5,6 and their ions can interact and bind with tumor cells' DNA to damage these diseased cells.…”

New two lanthanide complexes of Neodymium (III) and Gadolinium (III) ions were prepared based on 2‐Cyano‐N′‐([4‐oxo‐4H‐chromen‐3‐yl]methylene) acetohydrazide as a chelating agent. The prepared Nd(III) and Gd(III) complexes were characterized via elemental analysis, molecular conductance, IR, and TGA. The obtained results showed the chelating agent behaves as tridentate via oxygen of γ pyrone and carbonyl groups and nitrogen of the azomethine group. The antitumor activity of isolated complexes was investigated against the Ehrlich Ascites Carcinoma cell line (E.A.C). The results of antitumor activity cleared that Gd(III) complex has higher activity than Nd(III) complex and moderate activity relative to cisplatin and 5‐Furacil. Besides, DFT calculations were estimated for prepared Nd(III) and Gd(III) complexes by the Gaussian program. Theoretical parameters were calculated. The energy gap values confirmed the higher activity of the Gd(III) complex over the other Nd(III) complex. In addition, the composite films of Nd(III) and Gd(III) complexes were prepared using the cast technique. The electrical and optical absorption properties of these polymer composites were analyzed.
