• Abstract

  The use of molybdates as rare earth ion receptors has been studied for applications in optical devices, catalytic systems and antimicrobial agents. These applications are directly related to the high thermal stability of molybdate, which is a good receptor for trivalent ions, especially Eu3 +, an ion frequently used as a spectroscopic probe. These materials can be obtained by different ro…

• Abstract

  Silver tungstate (±-Ag2WO4) is a potential material in the field of science and technology due to its several applications, especially in the photoluminescence and photocatalytic field. Eu-doped silver tungstate can be a promising luminescent material since it emission spectra comprises a broad band in the blue region and narrow peaks in the red region. Moreover, new intermediary levels b…
