Book Description
"Nonlinear optical materials are a rapidly growing market and are expected to exceed $1.6 billion by 2007. Significant time, energy, and investment have been applied to increasing the efficiency of producing NLO materials. Of these materials beta-barium borate has stood out as an important NLO product. The goal of this research was the development of a novel beta-barium precursor suitable for applications in thin film technology. Special attention was paid towards development of a precursor suitable for metal organic chemical vapor deposition. To that end special attention was paid towards the synthesis of a mononuclear barium compound. The novel BBO precursor obtained was a barium dimesityl borate compound coordinated with 18-crown-6, barium (18-crown-6) dimesitylborinate (BaB2C48O8H68). The apparently water-sensitive precursor has shown conversion to BBO comparable to current industrial processes"--Abstract.

Book Description
This research developed two novel precursors for the formation of [beta]-BBO thin films using the metal organic decomposition (MOD) process. Advantages of using crown ether in the precursor solution were observed and recorded, including a lower temperature [beta]-barium borate formation and the ease of characterizing the precursor and its greater stability.

Book Description
Emphasis of our program during the past year has been on improving the size and quality of beta-barium borate (BBO) crystal, develop the growth recipe for lithium triborate crystal (LBO), characterization of LBO, develop BBO optical parametric oscillators, and finally help establish commercial sources of these crystals. Progress was made in all these areas. First, on the BBO crystal growth technology, we have now succeeded in growing relatively large single crystals of good quality (see Figure 1). The technology have now been transferred successfully to Cleveland Crystals Inc. They are now the first and only commercial source of domestically produced BBO crystals in this country and our program is receiving royalty income from their sales to support our research effort.

Book Description
A new class of volatile compounds of barium were synthesized. These 'capsule' compounds were prepared to saturate the coordination sphere of barium with one ligand. The covalent bonding of the polyglyme ligand to the 2,2,6,6-tetramethyl-3,5-heptanedione or similar ligand also increased the chelate effect, making loss of the glyme ligand on sublimation less likely. Single crystal X-ray crystal diffraction studies were done on these complexes. One of the complexes was used to grow BaTiO3 thin films to display the ability for these complexes to be used as metal organic chemical vapor deposition (MOCVD) precursors. Thin films of the superconducting material YBa2Cu3O 7-x were deposited on silver substrates by MOCVD. These films were analyzed by microscopy, and the electrical properties are discussed. The first reported growth of beta-BaBLO4 thin films by MOCVD is given. These films were grown on platinum, fused silica, sapphire, and silicon. Second harmonic generation of light from a Nd:YAG laser is observed in optical measurements.
