Band gap and superior refractive index tailoring properties in nanocomposite thin film achieved through sol–gel co-deposition method

Magnetic Properties of Mn‐doped SnO2 Thin Films Prepared by the Sol–Gel Dip Coating Method for Dilute Magnetic Semiconductors

“…Magnetic semiconductors are materials that exhibit both ferromagnetism and semiconductor properties. 8,9 Among the transition metals, much emphasis is being put on manganese (Mn) due to its large equilibrium solubility and nearly the same ionic radii as compared to Sn 4+ ion for substitution. 4 During the past few years, the DMS in which a small fraction of atoms/ions is magnetic have attracted considerable attention from both the fundamental as well as from the application point of view.…”

“…Many studies were reported in doping SnO 2 with antimony, indium etc. 8,9 Among the transition metals, much emphasis is being put on manganese (Mn) due to its large equilibrium solubility and nearly the same ionic radii as compared to Sn 4+ ion for substitution. The most common oxidation states of manganese are +2, +3, +4, +6, and +7, though oxidation states from À3 to +7 are observed.…”

“…SnO 2 :Mn films have been prepared by sol-gel method, which can be successfully used for the preparation of pure oxide films applied in electronics and optics. 8,9 In this work, we present the effect of structural, magnetic, electrical and optical properties by doping different concentrations of Mn in SnO 2 films produced by the sol-gel dip coating technique. .…”

Sol–gel zirconia nanopowders with α-cyclodextrin as organic additive

“…Although it has been extensively studied over few decades, the interest of the researchers is still increasing due to the wide range of its applications. The most spectacular ones include ceramics, bioceramics, refractories, piezoelectrics, pigments, cosmetics, solid electrolytes, oxygen sensors, active phases and/or supports in catalysis, columnpacking materials for high-performance liquid chromatography (HPLC), and photonics [1,[4][5][6][7][8][9][10][11][12][13].…”

“…The systems containing ZrO 2 are characterized by phase transformation reactions (of monoclinic polymorphic modification into tetragonal, of tetragonal modification into cubic, and/or by the formation of some intermediate metastable phases during these transformations). The high-temperature polymorphs cannot simply be quenched to room temperature because of their spontaneously martensitic transition to the monoclinic form [3,9,13]. When zirconia is obtained by conventional methods, it is often characterized by a mixture of monoclinic and tetragonal phases which, by coexisting, affect part properties of the product [4,17,18].…”
