Abstract: The La$_{1-x}$Eu$_x$VO$_4$ powders were synthesized by co-precipitation method. Luminescence spectra of the investigated samples consist of wide non-structural bands of the matrix emission and narrow spectral lines caused by inner f-f electron transitions in the impurity Eu3+ ions. The both types of emission were studied within 10 - 300 K temperature range. Obtained dependencies are discussed using proposed models for matrix emission and structure of the nearest surrounding of the Eu$_{3+}$ centers.
