摘要

A new non-centrosymmetric hydroxyl alkali metal borate LiNaRbB5O8(OH)(2) has been grown under mild hydrothermal conditions at 220 degrees C. LiNaRbB5O8(OH)(2) belongs to the orthorhombic space group Aba2, with a = 11.3017(5) angstrom, b = 10.9956(5) angstrom, c = 9.2860(4) angstrom, and Z = 2. The crystal structure of LiNaRbB5O8(OH)(2) consists of Li/Na-O, Rb-O polyhedra, and [B5O8(OH)(2)](3-) groups. The transmittance spectrum of the LiNaRbB5O8(OH)(2) exhibits an absorption edge less than 200 nm in the UV region. The powder second-harmonic generation coefficient in LiNaRbB5O8(OH)(2) is about one-third that of KH2PO4 (KDP) based the Kurtz-Perry method. First principle calculations based on band structure, density of states, and optical properties are used to better understand the relationship between electronic structure and optical properties.

LINARBB5O8(OH)(2)的晶体结构由LI / Na-O,RB-O Polyhredra和[B5O8 (OH)(2)](3-)组。 Linarbb5O8(OH)(2)的透射谱谱在UV区域中表现出小于200nm的吸收边缘。 粉末二谐波生成系数在LinarBB5O8(OH)(2)中是基于KurtZ-Perry方法的KH2PO4(KDP)的三分之一。 基于带结构,状态密度和光学性质的第一原理计算用于更好地理解电子结构与光学性质之间的关系。
