Summary: This review summarizes the recent developments of inorganic nano-crystalline Aluminoborates (ABOs) as UV and deep-UV nonlinear optical (NLO) materials. These ABOs can be classified into three types based on their compositions: aluminum oxyborates, alkali/alkaline earth metal aluminoborates, and alkali/alkaline earth metal aluminoborate fluorides and fluoroaluminoborates. The synthesis, structural features, NLO properties, and structure-performance relationships of these non-centrosymmetric ABOs are discussed, along with future perspectives in this field.

Summary: A new magnesium fluorooxoborate crystal with promising potential for deep-ultraviolet nonlinear optical applications has been synthesized, showing large nonlinearity and deep-ultraviolet phase matching wavelength, making it suitable for generating coherent light below 200 nm. The stability of the fluorooxoborate system with a general formula of MB5O7F3 (M=divalent metal) in retaining their crystallized space groups unchanged has been proposed. This demonstrates the critical performance enhancement compared to its isomorphic phases.

Summary: Inorganic heteroanionic materials have received increasing attention as potential nonlinear optical (NLO) materials due to their ability to simultaneously satisfy the necessary but conflicting properties of NLO crystals, such as large SHG response and wide band-gap. However, there has been limited research on chalcogenides containing different types of anionic groups. In this study, the first oxychalcogenide-carbonate, Sr-3[SnOSe3][CO3], was successfully synthesized, which contains two different types of anionic groups, [SnOSe3] and [CO3]. It exhibits fascinating NLO properties, making it a promising NLO crystal with a large SHG response, sufficient birefringence, wide band-gap, and high laser damage threshold.

Summary: Improving the non-linear absorption properties of graphene materials is crucial for optical limiting applications. The hybrid materials formed by non-covalent functionalisation of graphene nanoplatelets with pyrene-conjugated Zn(II) phthalocyanines and azaphthalocyanines show promising non-linear optical characteristics, such as three-photon absorption behavior and unique optical limiting performance. These hybrid structures offer a way to achieve large effective three-photon absorption coefficients and nearly constant optical limitation across a wide intensity range, which would be highly beneficial for non-linear photonic applications.

Summary: In this study, we propose a strategy to modulate the symmetry of MAPbI(3) single crystals (SCs) by heterogeneously integrating them with silicon (Si) wafers, and demonstrate the first self-powered near-infrared (NIR) polarization-sensitive photodetection using MAPbI(3) SCs. The MAPbI(3)/Si heterostructures show high crystalline quality and a solid interfacial connection. The built-in electric field at the MAPbI(3)/Si heterostructure interface generates polar symmetry, enabling directional transport of photogenerated carriers and making the heterostructures highly polarization-sensitive.

Summary: Two-dimensional hybrid perovskites, especially ferroelectric crystals, have great potential in optoelectronics as polarized light detectors. In this study, exceptional polarization responses to polarized light were achieved in ferroelectric crystals of (isopentylammonium)(2)CsPb2Br7. The alternate packing of organic spacers and inorganic sheets leads to its intrinsic optical dichroism, creating sinusoidal photocurrents with a polarization ratio of approximately 1.2 at 10 V bias. Notably, a large polarization ratio of approximately 7.2 can be obtained based on its bulk photovoltaic effect at zero bias (self-powered mode). This work sheds light on optimizing photoelectric behaviors in targeted optoelectronic device applications through ferroelectric bulk photovoltaic effect.

Summary: In this study, self-powered X-ray detection was successfully realized in a chiral-polar 2D lead-free halide double perovskite material, (R-MPA)(4)AgBiI8. The material displayed significant spontaneous electric polarization, resulting in a large polar photovoltage of 0.36 V, which facilitated the separation and transport of X-ray-generated carriers for self-powered detection. X-ray detectors based on high-quality single crystals of this material exhibited high sensitivity (46.3 mu CGy(-1) cm(-2)) and ultralow detection limit (85 nGy s(-1) at zero bias), outperforming current 2D lead-free halide double perovskite detectors. This work provides insights for the future design of green self-powered radiation detectors.
