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 routes of synthesis, among the most used methods, the relevance of the hydrothermal routes is verified. These routes are classified in: conventional hydrothermal method and microwave-assisted hydrothermal method. The microwave-assisted hydrothermal method emerged as an alternative to the problems reported in conventional chemical processing, such as the need for high temperatures and long processing times during the reaction. Microwave-assisted hydrothermal route preasents many operational variables that are directly related to the quality of the powders obtained, so, the general objective of this project is to optimize the temperature and reaction time parameters used in the synthesis of pure and doped ²-Ag2MoO4 with Eu3+, thus contributing to the understanding of the kinetic mechanisms involved and also to analyze the changes caused by microwave radiation in the structural, morphological and electronic properties of the obtained materials.
