      abstract     = {Polycrystalline CuMo$_{1-x}$W$_x$O$_4$ solid solutions were
                      studied by resonant X-ray emission spectroscopy (RXES) at
                      the W L$_3$-edge to follow a variation of the tungsten local
                      atomic and electronic structures across thermochromic phase
                      transition as a function of sample composition and
                      temperature. The experimental results were interpreted using
                      ab initio calculations. The crystal-field splitting
                      parameter Delta for the 5d(W)-states was obtained from the
                      analysis of the RXES plane and was used to evaluate the
                      coordination of tungsten atoms. Temperature-dependent RXES
                      measurements were successfully employed to determine the
                      hysteretic behaviour of the structural phase transition
                      between the alpha and gamma phases in CuMo$_{1-x}$W$_x$O$_4$
                      solid solutions on cooling and heating, even at low (x<0.10)
                      tungsten content. It was found that tungsten ions have
                      octahedral coordination for in the whole studied temperature
                      range (90-420 K), whereas their coordination changes from
                      tetrahedral to octahedral upon cooling for smaller (x<=0.15)
                      tungsten content. Nevertheless, some amount of tungsten ions
                      was found to co-exists in the octahedral environment at room
                      temperature for x<0.15. The obtained results correlate well
                      with the color change in these solid solutions.},
