Lithium fluoride is an interesting material because of its low refractive index and large band gap. Previously LiF thin films have been deposited mostly by phys. methods. In this study a new way of depositing thin films of LiF using at. layer deposition (ALD) is presented. Mg(thd)2(2,2,6,6-tetramethyl-3,5-heptanedionate) TiF4 and Lithd were used as precursors, and they produced crystalline LiF at a temperature range of 300-350 °C. The films were studied by UV-vis spectrometry, field emission SEM (FESEM), X-ray diffraction (XRD), at. force microscopy (AFM), time-of-flight elastic recoil detection anal. (ToF-ERDA), and energy dispersive X-ray spectroscopy (EDX). In addition, film adhesion was tested by a Scotch tape test. This method results in LiF films with a growth rate of approx. 1.4 Å per cycle. According to the ToF-ERDA measurements, the films are pure LiF with very small Mg and Ti impurities, the largest impurity being hydrogen with contents below 1 atom %.

Johns, Stephen C.; Crouch, Laurie L. E.; Grieve, Stephen; Maloney, Holly L.; Peczkowski, Gary R.; Jones, Allison E.; Sharp, Duncan; Smith, Robert B. published the artcile< A rapid, chromatography-free route to substituted acridine-isoalloxazine conjugates under microwave irradiation>, Recommanded Product: Pyrimidine-2,4,5,6(1H,3H)-tetraone hydrate, the main research area is acridine isoalloxazine conjugate preparation condensation microwave irradiation.

Microwave irradiation was applied to a sequence of condensation reactions from readily available 9-chloroacridines to provide a range of novel acridine-isoalloxazine conjugates. The combination of these two moieties, both of biol. interest, was achieved by a chromatog.-free route.
