Semiconductor-based X-ray detectors with low detectable thresholds become critical in medical radiography applications. However, their performance is generally limited by intrinsic defects or unresolved issues of materials, and developing a novel scintillation semiconductor for low-dose detection highly urgent objective. Herein, high-quality rare-earth iodate Tm(IO3 )3 single crystal grown through low-cost solution processing reported wide bandgap 4.1 eV large atomic number 53.2. The roles...
Pb(Mg1∕3Nb2∕3)O3-PbTiO3 (PMN-PT) crystals exhibit significant potential for applications in the electro-optical (EO) field, owing to their low half-wave voltage and high electro-optic coefficients, ease of miniaturization, integration. However, ferroelectric phase PMN-PT a extinction ratio due light scattering reflection by domain walls. In this study, high-transmittance paraelectric were synthesized through compositional optimization rare-earth ion doping. The optical Kerr properties...
The strategy of introducing large organic cations into three-dimensional perovskites could reduce the dimensionality to form quasi-two-dimensional (quasi-2D) perovskites, resulting in increased stability and reduced detection limits due less ion migration. Herein, a quasi-2D perovskite single crystal (BDA)(MA)2Pb3Br10 (BDA = NH3C4H8NH3, MA CH3NH3) with layered structure was grown by temperature-cooling solution method. X-ray detector based on has sensitivity as high 1984 μC Gy–1 cm–2 at 55.6...

As emerging materials for capacitor applications, antiferroelectric (AFE) possess high energy storage density. AFE single crystals are conducive to studying the physical mechanism of response. However, preparation is a huge and long-standing challenge. Herein, we report effect Na/La codoping on properties phase transition Pb(Lu1/2Nb1/2)O3 (PLN) crystals. An enhanced recoverable density 4.81 J/cm3 with efficiency 82.36% obtained, which much larger than that PbZrO3- PLN-based Two superlattice...
Dielectric ceramics are considered as promising candidates for high-temperature and pulse-power systems, due to their excellent thermal stability, mechanical performances, high energy storage characteristics. However, the potential of Pb(Lu1/2Nb1/2)O3 (PLN)-based antiferroelectric (AFE) in systems is limited by extremely phase transition switching field low efficiency. In this study, we propose a Ba2+/La3+ co-doping strategy enhance efficiency (η) while maintaining density. Compared...
