An X-ray diffraction (XRD) pattern for the as-synthesized phosphor material was recorded for structural analysis and phase identification. The diffraction peaks of the tungstate phosphor match very well with the standard JCPDS pattern. The optical band gap value of the as-synthesized phosphor has been measured using diffuse reflectance spectra (DRS). The photoluminescence (PL) spectral features recorded for the Dy3+ ions activated tungstate phosphor under 360 nm excitation reveal strong emission peaks in blue (490 nm), a relatively less intense peak in the yellow region (580 nm) and a significantly less intense red peak (683 nm). From the recorded PL spectra, the CIE chromaticity coordinates (0.33046, 0.37422) estimated for 1.0 mol% doping concentration of Dy3+ ions in the as-prepared phosphor material are falling in the white region. CCT value (5580K) signifies its application for cool white light-emitting diode (w-LEDs). The PL decay spectral profile recorded at 480 nm emission under 360 nm excitation shows double exponential behaviour. The temperature-dependent PL (TDPL) measurements demonstrate relatively better thermal stability for the as-synthesized phosphor. All the investigations carried out finally allow us to contemplate the suitability of Dy3+ ions doped tungstate phosphor for w-LED.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116755230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The facility delivers high brilliance, ultra-short, spatially coherent x-ray pulses with a high repetition rate to six instruments (FXE, SPB/SFX, MID, HED, SCS and SQS) by means of three different beamlines (SASE 1, SASE 2 and SASE 3). One of the first detectors used for early-stage experiments was the Adaptive Gain Integrating Pixel Detector (AGIPD), custom designed to meet the challenging needs of scientific instruments. The AGIPD is a megahertz-rate integrating hybrid megapixel camera with a per-pixel adaptive gain amplification, allowing the integration of up to 104 of 12 keV photons per pixel in its low gain stage. Currently, three scientific instruments, namely SPB/SFX, MID and HED employ the AGIPD systems, the latter mentioned using a prototype, half-megapixel camera with an upgraded version of readout ASICs. The AGIPDs at EuXFEL are successfully used for experimental techniques like serial femtosecond crystallography, MHz single particle imaging, MHz x-ray photon correlation spectroscopy or MHz diffraction of materials under high pressures in a diamond anvil cell. Since September 2017, the AGIPD is continuously used and has become an established detector technology, with further advancements and developments planned. Delivering quality experimental data requires reliable and reproducible detector characterisation and calibration that have to be performed regularly with a continuous improvement of correction methods in close collaboration with scientific instruments. This work summarises five years of experience operating the AGIPD detectors at the EuXFEL scientific instruments. It gives an overview of scientific capabilities and examples of successful studies performed with AGIPD detectors. Moreover, challenges concerning detector calibration and characterisation are presented.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114608739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several configurations have been proposed, using plane or concave gratings with uniform or variable line spacing. We propose here a low-cost experimental setup in which a thin plane diffraction grating is bended to an almost cylindrical shape to perform at the same time the spectral selection and the focalization of the selected spectral component. In such a way, the number of optical elements needed to realize the monochromator is reduced to two: the grating and the focusing mirror. A bendable grating has been tested in the 13-50 eV region, very good focal properties have been measured with very low residual aberrations. Furthermore, the shape of the bended surface has been measured using a wavefront sensor in order to confirm the effectiveness of the bending technique. The proposed solution can be used to achieve monochromatization both in large-scale facilities such as FELs or synchrotrons, but also in table-top setups, such as those exploiting high-order harmonic generation, that are often used for the preparatory phase of experiments to be later performed at FEL facilities.","PeriodicalId":376481,"journal":{"name":"Optics + Optoelectronics","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130524650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
