“…With the increase of Tb 3+ concentration, the T m does not shift, the intensity of the peak increases first and then decreases, and reaches the maximum when the Tb 3+ ion concentration is x = 1, which is consistent with the result of the PersL decay curve. The results show that the concentration of Tb 3+ ion does not affect the depth of the trap depth and can be estimated by formula () 24,25 :

E_{V} = \frac{T_{m}}{500}

The long persistent luminescence (PersL) and color adjustable properties in high‐temperature environment are of great significance for luminescent materials in the fields of multiple anti‐counterfeiting, biological imaging, and optical temperature sensing (OTS). In this work, a series of self‐activated CaNb2O6 (CNO): Tb3+ phosphors have been successfully synthesized by solid‐state reaction route, the OTS, and temperature‐dependent PersL of these phosphors is carried out and investigated in detail. Relying on the energy transfer from host to the activator Tb3+ ion, the visual color‐tunable emissions from blue to green were detected with the increase of temperature and the maximum absolute and relative sensitivities reach 0.955% K‐1 and 1.243% K‐1. Moreover, the temperature‐dependent PersL characteristics were investigated systematically, and the initial brightness and the lasting time all reach a maximum value at 323 K in the representative CNO: 1%Tb3+ sample. All the results show that the high‐temperature persistent phosphor has potential applications in OTS and anti‐counterfeiting field.

“…To our knowledge, terbium compounds can generally display excellent photoluminescence and, up to date, a great number of terbium compounds with interesting photoluminescent properties have been documented. [20][21][22][23] Therefore, for the sake of revealing the potential photoluminescent behavior, we carried out the photoluminescent experiments for compound 1 with solid state sample under room temperature. The measurement results of the photoluminescence experiments are depicted in Figure 4.…”

A new terbium complex, [Tb 2 (phenoxyacetic acid) 6 (H 2 O) 3 ] n •nH 2 O (1) with a two-dimensional (2D) layered structure, has been prepared via a hydrothermal reaction and structurally characterized by single-crystal X-ray diffraction technique. Compound 1 crystallizes in the space group Pī of the triclinic system with two formula units in one cell. Each terbium ion in compound 1 is coordinated by nine oxygen atoms to yield a monocapped tetragonal antiprism geometry. Photoluminescence spectra measured with solid-state sample of compound 1 demonstrate that the emission bands at 491, 545, 588 and 620 nm are observed from the 4f intrashell transitions of the Tb 3+ ions. These bands are originated from the 5 D 4 excited state to the 7 F 6 , 7 F 5 , 7 F 4 and 7 F 3 states, respectively. Solid-state diffuse reflectance spectrum reveals the existence of a wide optical band gap of 4.24 eV of compound 1.

“…For example, by doping Tb 3+ into Y 3 Al 2 Ga 3 O 12 host, three kinds of cross-relaxation energy transfer proceed: 5 D 3 → 5 D 4 and 7 F 6 → 7 F 0 , 7 D J → 5 D 1, 2, 3 and 7 F 6 → 5 D 4 , and 5 D 4 → 7 F 4 and 5 D 4 → 7 F 3 in Tb 3+ , which are blue, green and red emissions respectively. By tuning the doping concentration of Tb 3+ , an unchanged white PL was obtained and maintained for more than 2 h (Zhang et al, 2017). In 2015, Pan and co-workers extended the PL into the ultraviolet (UV) spectral region.…”

Crucial Breakthrough of Functional Persistent Luminescence Materials for Biomedical and Information Technological Applications

et al. 2019

Persistent luminescence is a phenomenon in which luminescence is maintained for minutes to hours without an excitation source. Owing to their unique optical properties, various kinds of persistent luminescence materials (PLMs) have been developed and widely employed in numerous areas, such as bioimaging, phototherapy, data-storage, and security technologies. Due to the complete separation of two processes, —excitation and emission—, minimal tissue absorption, and negligible autofluorescence can be obtained during biomedical fluorescence imaging using PLMs. Rechargeable PLMs with super long afterglow life provide novel approaches for long-term phototherapy. Moreover, owing to the exclusion of external excitation and the optical rechargeable features, multicolor PLMs, which have higher decoding signal-to-noise ratios and high storage capability, exhibited an enormous application potential in information technology. Therefore, PLMs have significantly promoted the application of optics in the fields of multimodal bioimaging, theranostics, and information technology. In this review, we focus on the recently developed PLMs, including inorganic, organic and inorganic-organic hybrid PLMs to demonstrate their superior applications potential in biomedicine and information technology.
