Structural and optical properties of 6CaO·6SrO·7Al2O3 thin films derived by sol–gel dip coating process

Novel hybrid PVA–InZnO transparent thin films and sandwich capacitor structure by dip coating method: preparation and characterizations

“…The observed transmittance values are in good agreement with early reported work on hybrid/composite thin lms based on In 2 O 3 , ZnO and TiO 2 . 6,46,58,59 The obtained high transmittance in the entire visible to infrared wavelength ranges are close to the reported value of transmittance for conventional glass substrate in literature. 60 Very low transmittance in the range between 290 nm and 340 nm indicates that these hybrid thin lms could be used for UV-blocking contact lens.…”

“…The obtained wide optical band gap energy values are in good agreement with early reported work on virgin In 2 O 3 / ZnO, hybrid In 2 O 3 /TiO 2 and indium zinc oxide based thin lms. 6,58,[63][64][65] From the Fig. 7, it is seen that the band gap energy value decreases with increase of annealing temperature.…”

“…79 The optical studies suggests that the optical properties of hybrid thin lms are signicantly affected by annealing temperature due to the improvement of the crystallinity of the hybrid lms with increase of annealing temperature. 58 3.5. Dielectric study Fig.…”

Enhancement of encaged electron concentration by Sr2+ doping and improvement of Gd3+ emission through controlling encaged anions in conductive C12A7 phosphors

“…[11][12][13] For example, Chavhan et al reported the structural and optical properties of 6CaOÁ6SrOÁ7Al 2 O 3 thin films and found that the transparency decreased with increasing Sr 2+ doping concentration. 14 In addition, the reported studies show that 12SrOÁ7Al 2 O 3 (S12A7) possesses a similar cage structure to C12A7 and a larger lattice constant (a = 1.233 nm) than C12A7 (a = 1.199 nm). 15,16 Thus, a strontium doping strategy might be a new way to modulate and enhance the conductive performance of C12A7 based powders through the hydrogen route.…”

Comparative Study of Morphology and Optical Properties of SrAl4O7 Nano- Phosphors

“…Many efforts have been made to discover host materials as well as activators with high performance for phosphor applications. Sol-gel method represents an attractive and easy alternative method to conventional synthesis method, such as ceramic firing [2][3][4], precipitation [5,6], or ion exchange on supported oxides [7]. The sol-gel process is an efficient technique for the preparation of phosphors due to the good mixing of starting materials and relatively low reaction temperature resulting in more homogeneous products than those obtained by direct solid state reactions.…”
