process for obtaining materials based on antimony and rare earth with chemical formula lnsb04, and their applications. the present invention describes a method for making materials based on antimony and rare earth lnsb0 with chemical formula 4, wherein "NL" represents rare earth elements of the series lantanídea, except cerium (EC) and promethium (MW). the methodology applied for the synthesis of the materials lasb04, prsb04, ndsb04, smsb04, eusb04, gdsb04, thsb04, dysb04, hosb04, ersb04, tmsb04, ybsb04 and involves a series of projectors lusb04 and details that must be employed to that final products are obtained crystalline and free of contaminants or secondary phases. the process to providing predicated on reaction in the solid state, through which is obtainable materials that are optically active 4 lnsb0 and function as host matrices for optical devices and luminescent.
