Barium Diketonates as Precursors for HTSC Thin Films : Structure and Properties
نویسندگان
چکیده
Homoligand and mixed ligand barium diketonate complexes have been synthesized and characterized by X-ray structure determination. Homoligand complexes with dipivaloylmethane hexafluoroacetone and pivaloyltrifIuoroacetone have oligigomeric or polymeric structure. The mixed complexes with additional anionic ligands (ClOH-, Piv-) form pentanuclear complexes. The structures of the mixed ligand complexes with Lewis bases contain either mono or dinuclear chelates. Deoligomerization is accompanied by a decrease of the sublimation temperature aud improves a storage stability of barium complexes used in MOCVD process for production of HTSC films.

Structural and Optical Properties of Sr-Modified Bismuth Silicate Nanostructured Films Synthesized by Sol Gel Method
In this work, the effects of strontium addition on the structure and optical properties of nanostructured bismuth silicate (Bi4Si3O12) thin films prepared via sol-gel were studied. At first, different sols containing the optimum ratio of precursors were synthesized, and then, the prepared sols were coated on the substrate via dip coating. The dip coated samples were dried at 100oC and, in order...

Nickel films with the thicknesses of 30 and 120 nm were deposited on glass substrates, at different substrate temperatures (313 to 600 K) under uhv condition. The nano-structure of the films and mean diameter of grains was obtained for each films using atomic force microscopy (AFM). Their optical properties were measured by spectrophotometry in the spectral range of 190-2500 nm. Kramers-Kronig ...
