Bifunctional Paramagnetic and Luminescent Clays Obtained by Incorporation of Gd3+ and Eu3+ Ions in the Saponite Framework. [PDF]
Inorg Chem, 2021 A novel bifunctional saponite clay incorporating gadolinium (Gd3+) and europium (Eu3+) in the inorganic framework was prepared by one-pot hydrothermal synthesis. The material exhibited interesting luminescent and paramagnetic features derived from the co-

Synthesis and characterisation of boron and gallium substituted saponite clays below 100 degrees Celsius and 1 atmosphere [PDF]
, 2005 This paper describes a simple procedure for the synthesis of saponites with isomorphous substitution of Si4+ by B3+ and Ga3+ below 100°C and at 1 atmosphere. The XRD patterns of the Ga- and B-substituted saponites are similar to Al-substituted saponites.
