“…The applications are extended from environmental monitoring, UV dosimeter for personal protection, food security, sensor, detector, on-board dosimetry in space, to antiterrorists by detecting nuclear or radiological weapons. [269][270][271][272][273][274][275][276][277][278][279][280][281] Most importantly, the more and more complicated modern radiotherapy, including intensity-modulated radiation therapy (IMRT) and stereotactic radiosurgery, imposes high level of challenges for dosimetric systems delivering dose evaluation with accuracy. The nature of high sensitivity of OSL material indicates that it will work at low dosage with high spatial resolution and accuracy.…”

Optically stimulated luminescence (OSL) materials, enabling energy storage by capturing of charge carriers and then the energy conversion to light via photostimulation, can find many advanced applications in various fields, spanning from radiation dosimetry, optical data storage and security, environmental monitoring, biomedicine, clinical diagnostic, to archaeology and geology. At present, there are some blocks, including the development of nanocrystallization approaches, the tailoring of optical transitions, the control of trap distribution, and the understanding of OSL mechanisms, on the road to the exploration of OSL materials. This review gives an overview of the design, preparation, characterization, optimization, application, mechanism, and prospect of OSL materials. A short introduction of the fundamental principle and history of OSL materials is presented, followed by a summary of preparation and design methods, and a survey of OSL materials reported to date. The trap engineering, mechanism, and study methodologies of OSL are summarized, after which the widespread applications of OSL materials, in traditional and newly emerging fields, are reviewed. Finally, the merits and drawbacks of the OSL materials according to the relevant reports currently available are examined. The challenges and outlooks are highlighted and discussed in terms of five important aspects that merit future research.

“…The proton-conducting oxides have a potential application in the fusion reactor's isotope separation systems [15,103,[152][153][154][155][156][157][158][159], hydrogen pump for tritium puri cation and recovery [160][161][162][163][164][165], and also as hydrogen sensors [31][32][33][34][35][36][37]and fuel cells [5][6][7][8][9][10]. Therefore, to advance in practical usage of oxide proton conductors as functional materials, it is essential to understand the hydrogen behavior in the proton-conducting materials, such as the amount of dissolution and internal diffusion of hydrogen [166][167][168][169][170]. Nevertheless, solubility and diffusivity data are limited and somewhat scattered for oxide materials.…”

There have been significant developments of solid-state-ion conducting energy materials and perovskite-based oxides those exhibit excellent proton conduction at intermediate temperatures. In contrast to high-temperature oxygen ion-conducting oxides or low-temperature proton-conducting polymers, perovskite oxides have obtained distinguished attention because of their diversified structural aspects and potential applications. Highly stable and conductive electrolytes with improved electrochemical and thermochemical properties are in great demand in numerous fields such as portable electronics and transport systems, energy storage, fuel cells, etc. This review focuses on recent development in the proton-conducting performance of BaZrO 3 (BZO) energy materials. This study aims to integrate the fundamentals of proton conducting BZO perovskites in the prospect of the recent development in materials science and computational engineering. Therefore, in the first half of this review, the basic overview of the BZO perovskites structure, fundamentals of working principles, fabrication, and processing methods underlying the successful development of these materials with superior performance is discussed. The second part principally concentrates on the significant improvement towards higher conductive BZO perovskite fabrication with the help of theoretical studies via density functional theory (DFT) based first-principles calculation and molecular dynamics (MD) simulation followed by the prominent applications in low-temperature solid oxide fuel cells. The presented information on in-depth analysis of the physical properties of barium zirconate from experimental and theoretical studies will guide aspirants in further conducting research in this field near future.

“…The disc shape specimen (diameter: 7.7 mm, thickness: 2.2 mm) was prepared using a conventional powder sintering method at 1923 K for 20h, which is described elsewhere [16,[21][22][23]. The SEM and EDX mapping were performed before and after polishing the sample to understand its surface properties.…”

“…As proton-conducting oxides are promising materials for electrochemical devices like fuel cell, hydrogen pump, hydrogen sensor, and for nuclear fusion reactor's tritium purification [9][10][11][12][13][14], recovery [10,[15][16][17][18][19], and monitoring system, therefore, the study of hydrogen behavior in such oxide materials is very fundamental and important. Yttrium (Y) doped barium-zirconate (BaZrO3) is a proton-conducting oxide that has a perovskite structure [20].…”
