摘要

持续发光（PersL）在显示、光学信息存储、生物成像和个性化医疗的头部检测等应用中发挥着重要作用。目前，在近红外（NIR）第二窗口（1000-1700 nm）具有优异性能的PersL材料的开发是一项具有挑战性但紧迫的任务，它可以为生物成像和生物传感提供高分辨率和深层组织穿透性。本文提出了一种通过引入定量阳离子空位来制造新型perl材料的策略。因此，定制的NIR PersL srgax4:Nd3+ (x <；2)通过连续引入非化学计量缺陷合成含Ga阳离子空位。此外，利用缺阳离子材料作为PersL宿主的设计理想可以作为一个强大的指南，加速发现具有更清晰机制的新型PersL材料。我们发现这种近红外PersL材料在生物成像和生物传感等领域的潜在应用前景广阔。

Nonstoichiometric cation engineering in SrGaxO4:Nd for near-infrared persistent luminescence

Persistent luminescence (PersL) plays an important role in applications such as display, optical information storage, bioimaging, and bead assays for personalized medicine. To date, the development of PersL materials with excellent performance in the second near-infrared (NIR) window (1000–1700 nm) is a challenging but urgent task that can provide high resolution and deep tissue penetration for bioimaging and biosensing. Here, A strategy for creating novel PersL materials by introducing quantitative cationic vacancies is presented. Hence, a tailored NIR PersL SrGa_xO₄:Nd³⁺ (x < 2) bearing Ga cation vacancies was synthesized by continuously introducing nonstoichiometric defects. Moreover, this design ideal guided by utilizing cation-deficient materials as PersL hosts can be used as a powerful guide to accelerate the discovery of novel PersL materials with much clearer mechanisms. Our discovery of this NIR PersL material offers prospects for potential applications in bioimaging and biosensing and beyond.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
