      abstract     = {The photochromic properties and charge transfer processes
                      were studied in novel Eu-doped M$_3$MgSi$_2$O$_8$ (M = Ca,
                      Sr, Ba) compounds. These materials exhibit vivid color
                      changes upon irradiation with UV light, resulting in orange,
                      reddish-pink, and green colors. The introduction of europium
                      ions enhances photochromic efficiency and shifts excitation
                      peaks to lower energy ranges. Analysis of diffuse
                      reflectance and electron paramagnetic resonance spectra
                      reveals the formation of both paramagnetic and
                      non-paramagnetic defects, with the dominant signals
                      attributed to electron centers, likely F$^+$-type centers.
                      The Eu$^{2+}$ → Eu$^{3+}$ charge transfer during
                      irradiation indicates that Eu$^{2+}$ acts as a hole center.
                      These findings contribute to a better understanding of the
                      mechanisms underlying photochromism in these materials and
                      highlight their potential for practical applications.},
