Abstract Fluorooxoborates, benefiting from the large optical band gap, high anisotropy, and ever‐greater possibility to form non‐centrosymmetric structures activated by polarization of [BO x F 4− ] ( +1)− building blocks, have been considered as new fertile fields for searching ultraviolet (UV) deep‐UV nonlinear (NLO) materials. Herein, we report first asymmetric alkaline‐earth metal fluorooxoborate SrB 5 O 7 3 , which is rationally designed taking classic Sr 2 Be B (SBBO) a maternal...

Currently, the fairly small birefringence MgF2 low transmittance α-BaB2O4 (α-BBO) hinder efficient application for wavelength below 200 nm. For example, deep-ultraviolet (DUV) light polarization urgently needed DUV lithography. Here we demonstrate based on...

KBe2 BO3 F2 (KBBF) is still the only practically usable crystal that can generate deep-ultraviolet (DUV) coherent light by direct second harmonic generation (SHG). However, applications are hindered layering, leading to difficulty in growth of thick crystals and compromised mechanical integrity. Despite efforts, it a great challenge discover new nonlinear optical (NLO) materials overcome layering while keeping DUV SHG available. Now, two NLO beryllium borates have been successfully designed...
Birefringent materials, the key components in modulating polarization of light, are great importance optical communication and laser industry. Limited by their transparency range, few birefringent materials can be practically used deep ultraviolet (DUV, λ < 200 nm) region. Different from traditional BO3- or B3O6-based DUV crystals, we propose a new functional gene, B2O5 unit, for designing materials. Excitingly, synergistic combination Li4B2O5 Na4B2O5 generates compound, Li2Na2B2O5, with...
A chemical cosubstitution strategy was implemented to design potential ultraviolet (UV) and deep-UV nonlinear optical (NLO) materials. Taking the classic β-BaB2O4 as a maternal structure, by simultaneously replacing Ba2+ [B3O6]3– units with monovalant (K+), divalent (alkaline earth metal), trivalent (rare-earth metal, Bi3+) ions, [B5O10]5– clusters through two different practical routes, 12 new mixed-metal noncentrosymmetric borates K7MIIRE2(B5O10)3 (MII = Ca, Sr, Ba, K/RE0.5; RE Y, Lu, Gd)...
Mid-IR nonlinear optical (NLO) materials are of great importance in modern laser frequency conversion technology and parametric oscillator processes. However, the commercially available IR NLO crystals (e.g., AgGaQ2 (Q = S, Se) ZnGeP2) suffer from two obstacles, low damage thresholds (LDTs) difficulty obtaining high-quality crystals, both which seriously hinder their applications. The introduction Cl, an element with a large electronegativity, Pb, relatively heavy to promote properties,...

Birefringent materials play indispensable roles in modulating the polarization of light and are vital laser science technology. Currently, design birefringent operating deep-ultraviolet region (DUV, λ ≤200 nm) is still a great challenge.

Birefringent materials are of great importance in optical communication and the laser industry, as they can modulate polarization light. Limited by their transparency range, few birefringent materials, except α-BaB2O4 (α-BBO), be practically used deep ultraviolet (UV) region. However, α-BBO suffers from a phase transition does not have enough UV By introducing relatively small alkali metal Na+ cation F– anion to keep favorable structural features α-BBO, we report new crystal Na3Ba2(B3O6)2F...
Birefringence plays a great role in phase matching of the nonlinear optical (NLO) crystals. Small birefringence restricts various crystals from achieving deep-ultraviolet laser output although they exhibit short UV cutoff edges and high second-harmonic generation (SHG) intensities. An access to achieve deeper coherent light through external pressure on NLO crystal, K3B6O10Cl is proposed demonstrated computer experiment based first principles theory. The “hot spot” structure that determine...
Sodium batteries (SBs) have aroused increasing attention due to the abundance and low cost of elemental sodium. In recent decades, intensive efforts been under way exploit advanced SBs for practical applications. However, conventional liquid electrolytes used in suffer from serious safety hazards (high volatility, inflammability, leakage), severe side reactions between electrodes electrolytes, inevitable sodium dendrite problems, which are greatly detrimental battery performance. Notably,...
In this study, we report a simple method to coat mesoporous silica onto carbon nanotubes (CNTs) via two-step procedure. Mesoporous CNTs@SiO2 composites have been obtained by extracting cetyltrimethylammonium bromide (CTAB) an ion-exchange procedure after silica-coated were synthesized with the aid of cationic surfactant CTAB. The coating process was explicitly investigated, and possible formation mechanism proposed, which reveals that ratio CTAB/CNTs plays critical role in process....
