Abstract

A new beryllium-free deep-ultraviolet (DUV) nonlinear optical (NLO) material, β-Rb2 Al2 B2 O7 (β-RABO), has been synthesized and characterized. The chiral nonpolar acentric material shows second-harmonic generation (SHG) activity at both 1064 and 532 nm with efficiencies of 2×KH2 PO4 and 0.4×β-BaB2 O4 , respectively, and exhibits a short absorption edge below 200 nm. β-Rb2 Al2 B2 O7 has a three-dimensional structure of corner-shared Al(BO3 )3 O polyhedra. The discovery of β-RABO shows that through careful synthesis and characterization, replacement of KBe2 BO3 F2 (KBBF) by a Be-free DUV NLO material is possible.

Beryllium Bohr ModelThe number of electrons in each of Beryllium's shells is [2, 2] and its electron configuration is [He] 2s2. The beryllium atom has a radius of 112 pm and a Van der Waals radius of 153 pm. Beryllium is a relatively rare element in the earth's crust; it can be found in minerals such as bertrandite, chrysoberyl, phenakite, and beryl, its most common source for commercial production. Beryllium was discovered by Louis Nicolas Vauquelin in 1797 and first isolated by Friedrich Wöhler and Antoine Bussy in 1828. Elemental BerylliumIn its elemental form, beryllium has a gray metallic appearance. It is a soft metal that is both strong and brittle; its low density and high thermal conductivity make it useful for aerospace and military applications. It is also frequently used in X-ray equipment and particle physics. The origin of the name Beryllium comes from the Greek word "beryllos," meaning beryl.
