“…Various routes of synthesis of Co 3 O 4 films have been undertaken such as chemical vapor deposition 8 , spray pyrolysis 9 , sol-gel method 8,10,11 , metal organic chemical vapor deposition (MOCVD) 12 . In this paper we have adopted a simple sol gel dip-coating method, this method of preparing thin films has several advantages: its low cost, flexibility in the deposition process, and it is convenient for a large area and it can produce homogeneous thin films with very regular crystallites sizes [13][14][15] .…”

In this article, Nickel doped Cobalt oxide thin films and powders have been prepared on glass substrates using sol gel based dip coating process in order to investigate their optical, structural and electrical properties. The Ni concentration was changed from 0 to 9 wt(%).The synthesized samples were characterised by Ultraviolete visible analysis, X-ray diffraction, Fourier transform infrared spectroscopy and Complex impedance spectroscopy to depict the optical, structural, vibrational and electrical properties. Our structural results show that the obtained samples were composed of (Co 3 O 4) polycrystalline with spinel-type preferentially oriented in the (311) plane. Our optical results show that the films have high transparency over the visible region (85% for Co 3 O 4 and ~ 60-75% for all doped samples). The optical band gaps were found to be (E g1 = 1.50 eV, E g2 = 2.20 eV) and (E g1 = 1.42 eV, E g2 = 2.07 eV) for the case of (pure Co 3 O 4 and 9% Ni-doped Co 3 O 4) respectively. The complementary phase information is provided by FT-IR spectroscopy. FT-IR spectra confirms the presence of Co 2+-O and Co 3+-O vibrations in the spinel lattice. The Nyquist plots suggests that the equivalent circuit of our films is an parallel circuit R p C p. It was found that the resistance Rp decreases whereas the capacity Cp increases with increasing doping levels.

Investigating the Colour Difference of Old and New Blue Japanese Glass Pigments for Artistic Use

et al. 2022

Colour consistency is an important consideration when selecting pigments used on works of art. In this study, we analyse the colour difference between two sets of synthetic blue glass pigments acquired at least 8 years apart from the same manufacturer in Japan. The old pigment set (unused, dry powder with four different grain sizes) appears faded compared to the new set. These pigments are made available for artistic use, commonly in Nihonga or Japanese paintings. Raman spectroscopy and SEM-EDS results characterize these pigments as cobalt aluminate spinels dissolved in leaded glaze, a special class of complex coloured inorganic pigments that is not well-understood in the field of conservation. Colour difference between the old and new pigments with four different grain sizes were quantified by analysing photomicrographs with image analysis software. Blue pigments with coarse and extremely fine grains showed significant colour change compared to pigments with medium and fine grain sizes. The high occurrence of crystallites in the finer grains give a final colour that is bluer and lighter. Possible causes for the colour difference including manufacturing methods and storage environment are discussed.

“…By means of the traditional preparation of the pigments, the size obtained after the calcination process is very high (>20 microns), for which a very energetic and expensive grinding stage is necessary. Use of different soft-chemistry synthesis routes has been used to develop particle size and to avoid or minimize the grinding stage [13][14][15], also the use of thermal decomposition of hydrotalcite-type compounds reduces this size in the final product, thus minimizing the energy consumption of the grinding process because of the adequate particle size obtained [11].…”

Development of ceramic pigments with controlled particle sizes below 1 µm is essential for the preparation of ceramic inks used in inkjet digital decoration that is currently being applied in the ceramics sector. A black ceramic pigment based on NiCoCrFe composition has been prepared using thermal decomposition of hydrotalcite-like compounds. The stoichiometry ratio between different cations was studied to obtain the blackest pigment, giving Ni0,5Co0,5CrFeO4 the better cation ratio, also the thermal treatment, comparing traditional firing in an electric furnace with microwave treatment. Samples have been characterized by X-ray diffraction, Scanning Electron Microscopy and Lab colour measurement. Microwave treatment showed the best way to obtain a pigment with spinel-type structure and a homogeneous size distribution near to 150 nm, with a high intensity and colorimetric data, reducing drastically the temperature and energy consumption to obtain a black ceramic pigment suitable to be utilized in digital ceramic inks.
