Summary: The article introduces a new concept for neutrino detection called LiquidO, which breaks with the conventional transparency paradigm by using an opaque scintillator and a dense array of optical fibers to confine and collect light near its creation point. This technique provides high-resolution imaging for efficient identification of individual particles event-by-event and a natural affinity for adding dopants at high concentrations.

Summary: This study demonstrates that (Z)-DVAM molecular crystalline microwires can exhibit continuous oscillatory motion when exposed to a combination of ultraviolet and visible light, mimicking the behavior of biological flagella. This is the first example of molecular crystals showing complex oscillatory behavior under continuous irradiation, with rotational frequency depending on light intensity and polarization.

Summary: All-thermal evaporation enables the fabrication of perovskite LEDs and active-matrix displays with high efficiency and resolution. A tri-source co-evaporation strategy with a multifunctional Lewis-base additive is developed to improve the quality of perovskite films. Green PeLEDs with a peak external quantum efficiency of 16.4% and active-matrix PeLED displays with high-definition images and videos are achieved.

Summary: Eu2+ activated rubidium calcium bromide scintillators were grown via the vertical Bridgman method, and their light yield, energy resolution, afterglow, and scintillation decay time were measured. It was found that increasing Eu2+ concentration improved the performance of the scintillators, with the highest light yields of Rb4CaBr6:Eu and RbCaBr3:Eu being 71000 and 45000 ph/MeV, respectively.

Summary: Efficient light extraction in perovskite X/gamma-ray scintillators is hindered by the small Stokes shift of exciton luminescence. Here, Jin et al. exploit the intrinsic strain in 2D perovskite as self-wavelength shifting to reduce the self-absorption effect without sacrificing the device response speed.

Summary: This study investigates the structural, elastic, optical, and electronic properties of CaQCl(3) (Q = Li and K) chloroperovskites using the DFT framework. The results show that CaLiCl3 is an insulator while CaKCl3 is a wide band gap semiconductor. These materials exhibit high optical activity in the ultraviolet spectral regions and can be used to alter or control electromagnetic radiation.

Summary: We suggest using a femtosecond X-ray pulse to trigger Resonant Auger scattering (RAS) in a distorted molecule, which provides information on the core-valence electronic transition and impresses a rich fingerprint of the electronic structure and nuclear configuration. By controlling the amount of molecular distortion with varied time delay, the RAS measurements imprint both their electronic structures and changing geometries. This work showcases a new alternative pump-probe technique for mapping the core and valence dynamics with ultrashort X-ray probe pulses.

Summary: This article discusses the issue of light propagation in metal halide scintillators, pointing out that the importance of light propagation in improving the conversion of X-rays to light has been overlooked. By studying the light propagation behavior in different forms of scintillators, this perspective summarizes and elucidates the design rules in this field, deepening the understanding of light propagation in metal halide scintillators.

Summary: The effects of composition on the phase formation of multicomponent garnet crystals grown via directional solidification by the micro-pulling-down method are studied. Crystals with large ionic radii have a central opaque region in optical microscopy images, which is responsible for their reduced transparency. Slow pulling rates can suppress the formation of the opaque region in crystals with intermediate ionic radii.
