Photoluminescence; Scintillator Photonics Single Photon Perovskites
Leading the Photonic Materials and Structures group within PORT is Dr. M. Danang Birowosuto (Senior member of Optica). He received a Ph.D. from Delft University of Technology and an M.Sc. in Applied Physics from the University of Groningen. During his doctoral studies in Delft, Dr. Birowosuto collaborated with Saint Gobain Crystals and Detectors to pioneer the development of lanthanide halide scintillators. This endeavor culminated in the creation of novel, high-performance lanthanide halides characterized by superior light yield and rapid nanosecond response times—a breakthrough that was patented in 2007 under the commercial moniker "Brillance". His tenure at Nippon Telephone and Telegraph, Japan, yielded the groundbreaking discovery of the first Purcell-enhanced telecom wavelength systems for emitters employing photonic crystals. Notably, he also devised a movable and tunable cavity, earning him the NTT Director\'s Award in 2014. Dr. Birowosuto served as a principal researcher and coordinator for one National Science Centre project of Poland and two Ministry of Education projects of Singapore, as well as a Thales-funded demonstrator, cumulatively valued at approximately €1.5M. In 2018, he successfully secured a world patent for perovskite scintillators. In total, Dr. M. D. Birowosuto has authored approximately 100 journal papers and 49 proceedings, featured in prestigious publications including Nature Materials, Science Advances, Advanced Materials, Physical Review Letters, ACS Photonics, and Scientific Reports. In total. In total, he supervised 6 Postdocs and 3 PhD students. Dr. M. Danang Birowosuto will support the applicants with the fabrication and photon pair characterization setup at PORT.
Title: Fast and bright Purcell-enhanced perovskite scintillator (FAPURITE). Host institution: Łukasiewicz-Port Source of funding: OPUS 24 Start and end date: 01-09-2022-01-09-2025 Project ID: 2022/45/B/ST3/03731 Amount of funding [currency]: 1 520 820 [PLN]. Short description of results of the project: We show potential over 10-fold emission rate enhancement and a 38 % reduction in time resolution for perovskite scintillators. Nanoplasmonics could increase light yield and average emission rate by over 120 % (88 ± 11 ph/keV) and 60 % (2.0 ± 0.2 ns), respectively, as predicted. The experimental work with perovskite scintillators marks the inaugural observation of the Purcell effect in ultrafast scale scenarios (0.7 ± 0.1 ns ultrafast-decay component) for scintillator system, indicating huge potential for time-of-flight soft X-ray imaging and photon-counting computed tomography. Demonstrated in a proof-of-concept soft X-ray imaging experiment, the scintillator device showcases remarkable imaging contrast and spatial resolution, approximately 182 % enhanced in the modulation transfer function at 4 line pairs per millimeter spatial frequency. These findings lay the groundwork for potent, efficient medical, industrial, and security imaging via nanoplasmonics and nanophotonic phenomena. The results are now in the preparation for high impact journal. Title: Light Matter Interaction for Better Optoelectronic Devices with Nanostructures in Perovskite Halides and Transition Metal Dichalcogenides. Host institution: Łukasiewicz-Port Source of funding: Starting grant Start and end date: 01-01-2022-On going Project ID: Amount of funding [currency]: 600 000 [PLN]. Short description of results of the project: Here we will improve properties of optoelectronic devices, e.g. radiation detectors, lasers, light-emitting diodes, and single photon emitters, so that they will have low energy consumption and less harm to the environment. The approaches based on the nanotechnology and the materials. The material choices limit to perovskite halides and transition metal dichalcogenides. So far, 3 journals were already published.
