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: KNO3SO3NH3 is a new polar non-centrosymmetric compound with a strong second-harmonic generation (SHG) response and large birefringence. The enhanced SHG response is attributed to the effect of hydrogen bond according to theoretical calculations. It also has the shortest absorption edge in the UV-visible spectrum among known materials with strong SHG responses.

Summary: This article explores the development of NLO phosphates from the perspective of structure-property relationships, focusing on the structural motifs and their impact on SHG effect, cutoff edge, and PM output. The study suggests that integrating [LiO4] or [MgO4]/[MgO5] groups into phosphates may be an effective strategy to achieve a good balance between SHG effect and cutoff edge.

Summary: Discovering new DUV nonlinear optical materials is a current research focus. However, integrating stringent performances, such as wide band gap and large NLO coefficient, into a crystal is challenging due to their natural incompatibility. This study proposes a boron-rich closed-loop strategy and successfully designs and synthesizes a new barium borate material, Ba4B14O25, which exhibits excellent NLO properties and holds promise as a DUV-transparent NLO candidate.

Summary: A strategy of structural diversity regulation was proposed to explore deep ultraviolet nonlinear optical fluorooxoborates with second harmonic generation phase-matching ability. By using the global evolutionary algorithm, stable fluorooxoborates were discovered in the Li(B2O3)(n)F ( n = 1, 1.5, 2, and 3) system, exhibiting large band gaps and birefringences, as well as large nonlinear optical coefficients. The ratio adjustment of pi-conjugated units and fluorine-based units, along with modulated layer flatness, facilitates the deep ultraviolet phase-matching capacity.

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: Deep-UV nonlinear optical (NLO) materials are crucial for demanding DUV laser applications, and the two synthesized fluoroaluminoborates exhibit NLO activity with short UV cutoff edges. Despite having the same fundamental structural units, their crystal structures and second harmonic generation (SHG) responses differ significantly due to the cation effect.

Summary: The paper proposes a general principle, pi-conjugated confinement, to partially decouple the interunit pi-conjugated interactions by separating non-pi-conjugated units, aiming to enlarge the band gap and gain a large optical anisotropy. This principle suggests that carbonophosphates could be a promising new DUV candidate system.

Summary: This study reveals two distinct self-trapped excitons (STEs) in 0D and 1D polymorphs of Cs3Cu2Cl5, which have the same chemical composition but different crystal structures, through first-principles calculations. The STE in 0D Cs3Cu2Cl5 involves the formation of one Cu-Cu bond and the breakage of two Cu-Cl bonds within an isolated [Cu2Cl5]3- unit, while the exciton self-trapping in the 1D structure is found to be associated with the formation of one Cu-Cu bond accompanied by two Cu-Cl bonds in the [Cu2Cl5]3- chain. Despite significant structural differences, the STE emission energies in both polymorphs are similar, which explains the similar green-light emission experimentally observed. This study provides important insights for understanding the complex relations between structural dimensionality, building units, and emission properties in low-dimensional metal halides.
