A combination of techniques is used to investigate the incorporation chromium in persistent phosphor LiGa<sub>5</sub>O<sub>8</sub>:Cr<sup>3+</sup>. Afterglow can be enhanced by codoping with Si(<sc>iv</sc>) or Ge(<sc>iv</sc>) ions.
Mn4+-activated phosphors are emerging as a novel class of deep red/near-infrared emitting persistent luminescence materials for medical imaging promising alternative to Cr3+-doped nanomaterials. Currently, it remains challenge improve the afterglow and photoluminescence properties these through traditional high-temperature solid-state reaction method in air. Herein we propose charge compensation strategy enhancing performance LaAlO₃ phosphors. LaAlO₃:Mn4+ (LAO:Mn4+) was synthesized by The...
Abstract Development of persistent luminescent materials has drawn continuous attention in recent years view their potential applications the fields security night-vision signage, vivo bio-imaging and optical data storage. Currently, normative evaluation a new material is focused on light emission spectrum, afterglow decay curve total duration time luminescence. In this paper, we investigate temperature dependent luminescence some well-known phosphors relate to thermoluminescence properties....
Persistent phosphors are increasingly investigated due to their potential applications in various fields, such as safety signage, dosimetry and vivo imaging. These materials act optical batteries that store gradually release energy supplied during charging. As the is stored, or 'trapped', at specific defect sites host lattice, a clear understanding of defects trapping mechanisms these important for systematic improvement properties. Here, thermoluminescence afterglow properties near-infrared...
The near-infrared emitting persistent phosphor LiGa5O8:Cr3+ (LGO:Cr) has promising applications in bioimaging. In order to improve the luminescence of LGO:Cr and other Cr-doped phosphors, a better understanding trapping detrapping mechanisms is necessary. this work, we study afterglow thermoluminescence via thermal fading experiment. results show that there broad trap distribution present LGO:Cr. emission spectrum chromium changes during afterglow, which indicates different Cr ions...
Abstract Dendritic cell (DC)‐based vaccines for immunotherapy have already achieved promising results in the last decade. To further improve current treatment protocols and enhance therapeutic outcome, noninvasive vivo tracking of DCs remains crucial importance. Persistent luminescent nanoparticles (PLNPs) are inorganic materials which show an afterglow hours after optical excitation has ceased. If is near‐infrared, emission injected particles can be tracked vivo. However, stability toxicity...
Persistent luminescent materials or glow-in-the-dark compounds have been known for centuries, but due to their limited performance in terms of total light output, they were never used large scale applications. It is only since about 20 years ago, when SrAl 2 O 4 :Eu,Dy was introduced as a new persistent phosphor [1], that leap forward both brightness and decay time achieved. This paper has initiated substantial research, which led an entire family materials, showing appreciable afterglow...
Since it was realized a few years ago that near-infrared emitting persistent or ‘glow-in-the-dark’ phosphors could be used for medical imaging applications, there is an active research interest in this class of compounds [1]. Persistent having emission spectrum the wavelength range between 650 and 950 nm, so-called first tissue transparency window, can injected applied as diagnostic therapeutic agents. To end, afterglow should bright long enough, particles bio-compatible. While most visible...
