Na_3TbSi_3O_9 centre dot 3H_2O:A New Luminescent Microporous Terbium(III)Silicate Containing Helical Sechser Silicate Chains and 9-Ring Channels

摘要

Microporous silicates hosting lanthanide elements have attracted considerable attention because such materials have high thermal stability,uniform microporosity,and a tunable optical property that may have many important applications.A number of lanthanide silicates were prepared under high-temperature and high-pressure hydrothermal conditions to search for fast alkali ion conductors.
