Recently, halide perovskites are considered as the new generation of radiation active materials due to excellent optoelectronic properties such as adjustable bandgap, high absorption coefficient, high carrier mobility and low cost. The radiation detectors based on perovskite show high sensitivity and low detection limit, contributing to excellent spatial resolution for imaging. However, the commercialization of perovskite radiation detectors for high quality imaging still faces many challenges, including ion migration in perovskite, fermi level pinning and electrochemical reaction at the interface of perovskite/electrode, and difficulties of integration with readout circuit. All the issues hinder the further improvement of device performance. This review summarizes the material forms and the optimized growth methods of perovskite for radiation imaging detectors. Further, this work focuses on challenges and improvements of the interface between perovskites and electrodes. Meanwhile, this work outlines the technical routes used to realize array detectors for radiation imaging. The comprehensive review would guide the commercialization of perovskite radiation detectors for high‐quality imaging.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"155 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still a challenge to extend the supercontinuum spectrum down to the deep‐ultraviolet (DUV) range, which is particularly needed for exploring ultrafast dynamics in chemistry, materials, and biology. Here, an approach of non‐resonant coherent Raman scattering is developed to generate ultra‐broadband visible‐DUV supercontinuum in ambient air with a spectral range spanning over 250 nm and a wavelength down to 220 nm. A rovibrational coherence is established in air molecules by filamentation of a near‐infrared femtosecond 800 nm pulse and two femtosecond Raman laser pulses at 267 and 400 nm are introduced into the coherent media to induce non‐resonant coherent Stokes and anti‐Stokes Raman scatterings, which serve as the spectral bridges to link the neighboring Raman pump laser spectra, resulting in ultra‐broadband supercontinuum light. The mechanism is further verified by examining the broadening of picosecond N2+ laser lines with narrow bandwidths (10–30 cm−1), which forms a supercontinuum spectrum spanning over 150 nm. The work provides a viable route for the establishment of coherent DUV supercontinuum in the gas media at designed wavelength ranges.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"6 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most ML materials are focused on the UV–vis light range, which limits their potential applications in the biological field. In this work, a broadband NIR ML material Ca2YGa3Ge2O12: 0.10Cr3+ (CYGGG: 0.10Cr3+) is successfully prepared by chemical co‐substitution and Cr3+ heavy doping. Density functional theory (DFT) calculations are used to determine the type of defects in the material, and the composite defects formed by interstitial oxygen (iO′′) and antisite defects (CaY′ ‐ YCa°) mostly dominate NIR ML. Cr3+ ions act as electronic bridges to regulate energy levels, becoming the key to turning on the Nd3+ ion's NIR ML. Finally, based on the excellent ML properties of CYGGG: 0.10Cr3+ and CYGGG: 0.10Cr3+, 0.01Nd3+, the ML composites can penetrate pork tissues of different compositions/thicknesses under stress loads. Potentially, this work tries to realize biological tissue stress imaging, providing a new way for the biological application of NIR ML materials.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"150 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manganese (Mn)‐based inorganic–organic hybrid materials are distinguished by their thermal stability, mechanical strength, and flexibility. However, the effects of temperature on Mn(II)‐based hybrid scintillators have not been clearly analyzed, making the elucidation of their temperature‐dependent luminescence mechanisms particularly important. A notable advancement is the synthesis of Mn‐1 nanocrystals (NCs) using methyltriphenylphosphonium chloride (mtppCl) and MnCl₂. These NCs exhibit distinctive temperature‐dependent photoluminescence luminescence: the intensity decreases from 77 to 150 K but paradoxically increases at higher temperatures due to anomalous thermal exciton behavior in the [MnCl₄]2⁻ tetrahedra. Besides, Mn‐1 NCs achieve a detection limit of 1.01 µGyair/s, surpassing medical diagnostic standards and outperforming commercial scintillators such as Bi₄Ge₃O₁₂ (BGO). Additionally, they show exceptional stability under continuous irradiation and can be incorporated into a flexible scintillating film with a resolution of 11.3 lp/mm at an MTF of 0.2. The current study has further refined the luminescence mechanism of Mn(II)‐based materials and optimizes their properties for a wider range of applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"13 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This integrated chip is composed of a set of perfectly vertical grating couplers, interleaved angled‐MMI wavelength division (de)multiplexers, silicon E‐O modulators, and germanium waveguide photodetectors. The multiplexer exhibits an IL of (4.5–5.8) dB and average crosstalk ≈−20 dB. Due to the limited bandwidth of the 2‐D GC, the IL of the demultiplexer is 5.17 dB at minimum, with a channel nonuniformity of 5.53 dB. The EO modulator and germanium waveguide PD exhibit 3‐dB bandwidths of 45 and 47 GHz, respectively. With a customized fiber array packaged, a back‐to‐back data transmission capacity of 1.56 and 1.42 Tb/s with BERs below the SD‐FEC limit is demonstrated for the transmitter and receiver, respectively. By connecting the transmitter and receiver, the dynamic performance of the transceiver chip is characterized, and the total data capacity of eight wavelength channels is 1.18 Tb/s. To show the advantage of transmission distance, 2 and 10 km SMF transmission experiments are also carried out.
