For so doing, different coatings have been prepared in various conditions and their microstructures have been correlated with the synthesis parameters as well as the physical properties. Chromium oxide films on nickel-coated copper metallic substrates have been deposited from a chromate bath. In this paper, we present the evolution of the microstructure of the deposits according to some experimental parameters, more specifically the concentration of the hexafluorosilicic acid and trivalent chromium ions present in the electrochemical bath used in our experiments. A marked difference in the particle morphology has been put into evidence by modifying the source of the trivalent chromium ions: (i) from the addition of sucrose to the solution containing hexavalent chromium ions or (ii) from the addition of a trivalent chromium salt to the bath.</div>","PeriodicalId":100700,"journal":{"name":"International Journal of Inorganic Materials","volume":"3 8","pages":"Pages 1323-1329"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1466-6049(01)00154-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87967320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the low or moderate temperature diffusion processes the X-cuts, which are parallel to the C3 axis, always contained much more dopants comparing with the Z-cuts, which are oriented perpendicularly to the C3. This has been proved for annealed proton exchange (APE) technology for fabrication of optical waveguides in lithium niobate and for the moderate temperature incorporation of erbium ions into both materials. Thus the possibility of localized doping by Er3+ diffusion at moderate (lower then 500°C) temperature is for the first time demonstrated for sapphire single crystal wafers. The strong anisotropy of the doping is explained on the bases of suitable orientation of the cleavage planes to the substrates surfaces in the X-cuts that allows for better penetration of the diffusing particles into the material.</div>","PeriodicalId":100700,"journal":{"name":"International Journal of Inorganic Materials","volume":"3 8","pages":"Pages 1245-1247"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1466-6049(01)00150-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89427728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
