      abstract     = {ABSTRACT: This study explored the influence of Sc$^{3+}$
                      ions incorporation on the structural, vibrational,
                      luminescent, and scintillation properties of Pr$^{3+}$-doped
                      Lu$_3$(Al,Sc)$_{2.5–x}$Ga$_{2.5–x}$O$_{12}$ garnet
                      crystals. Addressing the limited research on Sc-admixed and
                      Pr$^{3+}$ doped garnet systems, this work successfully
                      demonstrated the crystallization of garnet crystals from the
                      melt, overcoming the substantial atomic mismatch between Sc
                      and Al while preserving the thermodynamic stability of the
                      garnet phase. Importantly, Sc-admixing enhanced atomic
                      homogeneity and allowed for increased doping concentrations
                      of Pr$^{3+}$ ions, which is crucial for tailoring the
                      functional properties of advanced optical materials.The trap
                      depths ranged from 1.63 eV (deep traps) to 0.22 eV (shallow
                      traps) across all samples, with frequency factors
                      predominantly between 1 × 10$^7$ and 1 × 10$^{11}$
                      s$^{−1}$, consistent with first-order thermoluminescent
                      kinetics. From a materials design perspective, Sc$^{3+}$
                      ions substitution induced beneficial host lattice disorder,
                      enhancing the emission intensity of 4f$^1$5d$_1$ $^1$ →
                      4f$^2$ interconfigurational and 4f$^2$ → 4f$^2$
                      intraconfigurational transitions. This effect highlighted
                      the potential of Sc as a promising substituent for enhancing
                      the luminescence intensity of rare earth
                      elements.Synchrotron radiation experiments provided insights
                      into the impact of Sc on band gap energy and energy transfer
                      efficiency toward Pr$^{3+}$ ions offering new opportunities
                      for engineering scintillators and phosphors with tunable
                      optical properties.},
