“…事实上，有关 Cu 离子掺杂材料的辐射发光现象早已被广泛研究，不过多集中在 TSL、OSL 和闪烁发光，基于 RPL 特性的研究有限 [42] 。大多数 Cu 离子掺杂体系的 RPL 材料能够显示良好的化学耐久性，但由于较低的辐射探测灵敏度，并不适用于个人剂量监测，但在大剂量监测方面具有较大的应用潜力。 Hashikawa 等 [42] (a) Schematic diagram of RPL/OSL/TSL general luminescence mechanism [13] ; (b) Excitation and emission spectra of Ag-PG [7] ; (c) Emission spectrum of Ag-PG under different doses of X-ray irradiation [52] ; (d) Excitation spectrum (pink dotted line) and emission spectrum of Ag-Rb glass before and after X-ray (10 Gy) irradiation [54] ; (e) Emission spectra of Ag-Nd co-doped phosphate glass at different radiation doses (310 nm excitation) [55] ; (f) Excitation spectrum (dashed line) and emission spectrum (solid line) of Ag-doped CsCl before and after X-ray irradiation [59] ; (g) Excitation and emission contour spectra of Al2O3:C,Mg irradiated by β-rays ( 90 Sr/ 90 Y) [63] ; (h) Excitation spectrum and emission spectrum of LiF after X-ray irradiation (126 Gy) [64] ; (i) RPL defect center in LiF, where F3 + is formed by three anionic vacancies capturing two electrons and F2 is formed by two anionic vacancies capturing two electrons [7] 随后， Hashikawa 等 [66] [68] 。Sm 离子是目前研究最多的镧系元素， Sm 离子掺杂体系的 RPL 特性于 21 世纪初被发现，但最初并没有用于辐射剂量学，而是用于高密度的光学存储器 [7] 。直到 2011 年，Okada 等 [69][70] 才将 Sm 离子掺杂材料用于 X 射线微束的剂量分布检测。基于 Sm 离子掺杂的 RPL 材料体系有许多，主要包括氟磷酸盐、氧化物、氟氧化物和卤化物等，但实际只有少部分能够表现出 RPL 特性。特别需要指出的是，Sm 离子掺杂材料具有极大的剂量范围 (mGy~kGy)，且大部分材料具有较好的辐射灵敏度和可循环使用性等特点 [32,34,71] 。此外，Sm 离子掺杂材料记录的 RPL 信号极其稳定，几乎不会衰退。同时，辐照后产生的 RPL 信号具有极短的积聚时间，因此适用于辐射剂量的实时监测。在 Sm 离子体系的化合物中， Sm 离子在二价和三价下均具有稳定的氧化态，但它们却拥有不同的电子架构。基态下的 [7,32,72]…”

With the progress of nuclear radiation technology in China, radiation detection has been developed rapidly in recent years, which is widely used in radiation safety monitoring, radioactive medicine diagnosis and treatment, X-ray security inspection system, industrial non-destructive detection, microscopic particle track detection and many other fields. As a new radiation detection method, radio-photoluminescence (RPL) is a phenomenon in which a new luminescence center is generated inside a material under the ionizing radiation and is excited by ultraviolet light to emit light. RPL materials usually have the characteristics of storing radiation information, almost no attenuation of information, good linear dose response, high radiation 无机材料学报 sensitivity, low energy dependence and repeatable reading, which make up for the shortcomings of optically stimulated luminescence (OSL) materials and thermally stimulated luminescence (TSL) materials in storage stability and reusability. Since the RPL phenomenon was reported, RPL materials have emerged one after another, from the traditional materials as Ag-doped phosphate glass, Al2O3:C,Mg and LiF, to the novel materials as Cu-doped RPL system, Sm-doped RPL system and undoped RPL system materials, et al. Meanwhile, the applications of RPL materials have also been explored. RPL materials have become one of the indispensable materials in the field of radiation detection. Based on this, this paper summarizes the latest development of RPL materials, focuses on the luminescence principle, performance characteristics and applications of traditional & novel RPL materials. It especially compares the performance of different RPL materials in radiation detection. Finally, the advantages and disadvantages of RPL materials are summarized and analyzed. And also the development trend of RPL materials is prospected.

“…The characteristic absorption peak for Ag-nanowires synthesized by any method is reported from 300-440 nm ranges which is due to the oscillation of electrons in the conduction band [44,45]. Moreover, the trapped electron can also be involved in intra-center transitions between Ag 0 /Ag + , due to which the absorption band could appear in the 440-550 nm range [46]. It is clear from spectra that there is no peak in Psidium Guajava seed extract solution which illustrates the absence of Ag-NWs.…”

Herrin, a simple and eco-friendly method for the synthesis of silver nanowires (Ag-NWs) has been reported. Silver nanowires were synthesized using Psidium guajava seed extract that acted as a reducing agent as well as a stabilizing agent for silver nitrate solution. Synthesis was carried out at 50 °C temperature under continuous UV-irradiation. Silver nanowires were initially characterized by a UV-visible and FTIR spectrophotometer. In addition, morphology and particle size of synthesized Ag-NWs were determined using Field Emission Scanning Electron Microscopy and X-ray diffraction (XRD) techniques. Nanowires were found to have 12.8 μm length and 200–500 nm diameter and cubic phase morphology. Furthermore, the catalytic potential of Ag-NWs for the degradation of methyl orange dye (MO) was determined. The selected dye was degraded successfully that confirmed the catalytic potential of Ag-NWs. The authors concluded that Ag-NWs can be synthesized using plant extract having excellent morphological features as well as impressive catalytic potential.

“…There are two types of dosimeters classified by different ways (energies) to stimulate carriers; thermally stimulated luminescence (TSL) dosimeter uses thermal stimulation, [12][13][14][15][16][17] and optically stimulated luminescence (OSL) dosimeter utilizes light stimulation. [18][19][20][21][22] In contrast, some dosimeters use a phenomenon called radio-PL, [23][24][25][26][27][28][29][30] in which luminescent centers corresponding to the irradiation doses are generated newly, and RPL can be easily measured by a PL technique. The most prominent RPL material is Ag-doped phosphate glass (RPL glass).…”

Au nanomaterials are known to change their properties significantly depending on their particle size. The prepared chloride glasses exhibited yellow emission (520 nm) upon UV rays (250 nm) irradiation, and the intensity of emission was found to decrease with X-ray dose. We concluded that this is because luminescent Au nanoclusters (AuNCs) of a few nanometers in size grow into Au nanoparticles (AuNPs) of a few tens of nanometers in size due to the photoreduction effect induced by irradiating X-ray, and the absorption (550 nm) attributed to the surface plasmon effect of AuNPs make decrease the AuNCs emissions. From the results of the changes of photoluminescence (PL) intensity concerning the irradiation X-ray dose, it was found that the PL intensity monotonically decreased 3000 mGy or more. This suggests that the Au-doped CsCl–BaCl2–ZnCl2 glass can act as an X-ray detection material in a specific dose region.
