“…Lanthanide-doped luminescent materials with tunable trap structures and varied crystal topologies produce fascinating optical phenomena. Among them long persistent luminescence (LPL) as a peculiar optical phenomenon for luminescence, lasting for seconds, minutes or even hours after the excitation source is removed, has been explored for practical applications in bioimaging, 1–7 sensing, 8–10 and information storage. 11–13 In particular, phosphors with LPL at low temperature provide a novel approach for applications in extreme conditions like polar exploration and vaccine cryopreservation.…”

“…On the other hand, the afterglow intensity of ZGGO:Cr 3+ ‐based nanoparticles will decay fast with time after stopping charging by X‐ray, ultraviolet (UV), or visible light, and this will result in poor afterglow imaging for long‐term diagnosis and therapy of tumors. Recently, X‐ray, UV (254 nm), or red (635 nm) light irradiation in combination with a subsequent 808‐ or 980‐nm laser re‐excitation strategy was employed to realize the reoccurrence of long‐term in vivo imaging using ZGGO:Cr 3+ nanoparticles 4–6,25–29 . However, for UV and visible wavelengths, their tissue penetration is shallower than those falling in the first, second, and third NIR biological transparent windows.…”

“…Thus, UV and visible reirradiations cannot recharge the related traps and recover NIR afterglow imaging in the case of deep tissue. For X‐ray light, despite it has deep penetration depth, in order to avoid the possible radiation damage and carcinogenic risk, its irradiation dose is essential to decrease to close to or below the safe dose limit, that is, 20 mSv per year recommend by ICRP (International commission on radiological protection) 4,26,27,30 . In the case of low‐dose X‐ray irradiation, how different NIR lights re‐excitations, such as wavelength and power density, influence the upconverted persistent luminescence is still unclear.…”

Herein, Cr3+ and Er3+ codoped zinc gallogermanate (ZGGO) nanoparticles with average size of ~60 nm was synthesized via a hydrothermal path. It was found that near infrared (NIR)‐III (~1540 nm) afterglow was realized in ZGGO:Cr3+,Er3+ nanoparticles based on the successive energy transfer (ET) from Cr3+ to Er3+ after the stoppage of low‐dose (60 mSv) X‐ray irradiation. Meanwhile, the upconverted afterglow at 696 nm was produced via the ET from Er3+ to Cr3+ under different NIR light (808, 980, and 1532 nm) irradiations. Our results demonstrated that an X‐ray pre‐irradiation and a subsequent 980‐nm light re‐excitation might be a good strategy for realizing potential bioimaging. In particular, local‐tissue NIR‐I afterglow imaging using Cr3+ and Er3+ codoped ZGGO nanoparticles can be easily acquired by one‐step 980‐nm laser radiation. Furthermore, NIR‐I/III afterglow mechanisms of ZGGO:Cr3+,Er3+ nanoparticles after stopping X‐ray or different NIR lights (808, 980, and 1532 nm) irradiations were given.

Among various energy storage materials, long persistent phosphors (LPPs) are a class of "optical battery" that can emit luminescence continuously for a long time after the removal of excitation sources. [6] Since the report of greenemitting SrAl 2 O 4 :Eu 2+ , Dy 3+ LPPs in 1996, [7] a large variety of LPPs have been rapidly developed and widely used in security signs, displays and in vivo biological imaging, to name just a few. [8][9][10][11][12][13][14][15] Among these phosphors, representative ones with excellent afterglow properties are CaAl 2 O 4 :Eu 2+ , Nd 3+ , [16] Y 2 O 2 S:Eu 3+ , Mg 2+ , Ti 4+ , [17] and Zn 3 Ga 2 Ge 2 O 10 :Cr 3+ , [18] which emit in the visible and near-infrared spectral regions. [19][20][21][22][23] In marked contrast, the research and development of UVC LPPs relatively lag behind, although such phosphors hold great potential in terms of sterilization, drug release, and cancer therapy. [24][25][26] To date, only a handful of UVC LPPs have been successfully developed, and all of them involve the use of rare-earth (RE) ion, Pr 3+ , as the UVC emitter. [25,[27][28][29] Given that REs are expensive due to the limited abundance in the earth and great imbalance between supply and demand, it is imperative to explore and develop non-REenabled UVC LPPs, which may not only enrich the bank of LPPs, but also offer new opportunities for rationally designing non-RE-activated phosphors.The ingredients for designing LPPs involve the choice of suitable emitters, hosts, and traps for either electrons or holes. The emission wavelength of LPPs is governed by the emitter [30] and the afterglow duration and intensity depend on the species and concentrations of traps with suitable depths; [31] in most cases structural defects can be employed as charge carrier traps. [6] As a result, to obtain a non-RE UVC persistent phosphor, using a non-RE luminescence center that can emit UVC light and choosing a suitable matrix with appropriate defects must be satisfied simultaneously. Bismuth, with the electronic configuration of [Xe] 4f 14 5d 10 6s 2 6p 3 , is one of the most investigated main-group elements, which has been known as nearly fullspectrum luminescence ions due to the existence of multiple oxidation states and the propensity for the formation of clusters. [32][33][34][35][36] In recent years, Bi 3+ -doped LPPs have received wideranging attention and been considered as potential alternatives to RE-doped cousins. [37][38][39][40] For instance, previous works revealed that Bi 3+ -doped LiYGeO 4 and LiScGeO 4 show ultraviolet-A afterglow, [37,38] Bi 3+ -doped KGaGeO 4 and CaGa 2 O 4 show blue and Long persistent phosphors (LPPs) have drawn tremendous research interest owing to their mysterious optical phenomena and widespread applications. LPPs in the ultraviolet-C (UVC, 200-280 nm) spectral range particularly hold promise in terms of sterilization, drug release, and cancer therapy. However, all reported UVC LPPs have so far relied on the use of Pr 3+ as the emitter, resulting in a limited scope of such phos...
