Preparation of crystalline ZnSnO3 from Li2SnO3 by low-temperature ion exchange

Transparent conducting properties of SrSnO3 and ZnSnO3

“…[6][7][8][9][10][11][12] The related compounds, CaSnO 3 and SrSnO 3 , occur in distorted orthorhombic perovskite structures, 26 while ZnSnO 3 occurs in a ferroelectric LiNbO 3 type structure. 13,[27][28][29][30] Amorphous zinc-tin-oxide amorphous films were already been successfully developed for transparent electronics ten years ago, 31 while mixed phase films with compositions near ZnSnO 3 are known to show good TCO properties. 32,33 Nonetheless, indium containing amorphous In-Ga-Zn-O (IGZO) films is dominant in technological applications of transparent amorphous oxide electronics due to their performance.…”

Obtención de materiales cerámicos basados en ZnO-SnO₂ por coprecipitación

“…As observed, above 1000ºC the system is composed by a mixture of two phases, the major ZnO and a spinel type phase corresponding to Zn 2 (5), whereas other authors ascribed it to single ZnSnO 3 phase (4). In an attempt to clarify this feature TEM micrographs of powders calcined between 600 and 900ºC were performed.…”

“…For example Sheng and Zhang obtained a pure ZnSnO 3 phase with a perovskitetype structure by using a co-precipitation method with oxalic acid and ammonia as precipitants (4). Looking into the ionic radius of Zn 2+ , Kovacheva et al however stated that ZnSnO 3 cannot adopt a perovskite structure under normal conditions, and by means of a low-temperature ion exchange technique (using Li 2 SnO 3 and ZnCl 2 ) they prepared ZnSnO 3 with an ilmenite-type structure (5). Any other attempt to prepare pure ZnSnO 3 by different methods has failed but in any case, if crystalline ZnSnO 3 exists, it should be exhibiting a limited thermal stability as the only stable phases at high temperatures in the ZnO-SnO 2 system seem to be Zn 2 SnO 4 , ZnO and SnO 2 (6).…”

Photovoltaic Properties of Dye Sensitized Solar Cells Employing Amorphous ZnSnO₃ as a Semiconducting Porous Film Material

“…Three methods have been reported for the synthesis of ZnSnO 3 . Firstly, ilmenite-type ZnSnO 3 may be synthesized by the ionic exchange of Li 2 SnO 3 in molten salt containing Zn [6]. Secondly, amorphous ZnSnO 3 can be obtained by pyrolysis of ZnSn(OH) 6 [7] and, lastly, LiNbO 3 -type ZnSnO 3 may be produced using a high pressure technique [8].…”

“…In the present study, a photoelectrode was fabricated using a ZnSnO 3 film formed by applying a paste containing ZnSn(OH) 6 followed by sintering. The photovoltaic properties of the dye sensitized solar cells incorporating this photoelectrode were subsequently investigated.…”
