      abstract     = {The photoluminescence and radioluminescence investigation
                      of zinc-silicate glass-ceramics doped with Ho3+ or Tm3+
                      ions, co-doped with Yb3+ ions, and containing Zn2SiO4
                      (willemite) crystalline phase are presented. The precursor
                      glasses were prepared by traditional melt-quenching, the
                      glass-ceramics were prepared by controlled heat treatment of
                      the glass. The structure of the resulting glass-ceramics was
                      determined by X-Ray Diffraction and Transmission Electron
                      Microscopy, which confirmed the crystallization of Zn2SiO4.
                      The glass-ceramics were analyzed with respect to the
                      photoluminescence properties of Tm3+ and Ho3+ ions. The
                      glass exhibited typical emissions around 2 μm stemming from
                      the Ho3+ or Tm3+ ions, and the intensity of the emission was
                      increased by up to 350 $\%$ for Ho3+/Yb3+ and 280 $\%$ for
                      or Tm3+/Yb3+ by the crystallization. The virgin glasses
                      exhibited longest values of lifetime of 1.596 ms for
                      Ho3+/Yb3+-doped samples, and 0.877 ms for Tm3+/Yb3+-doped
                      samples. The crystallization of Zn2SiO4 crystalline phase
                      resulted in radioluminescence around 350 nm after the X-ray
                      excitation. The radioluminescence lifetime of samples
                      containing Zn2SiO4 was approximately 30 ns. Although no
                      obvious interaction between the rare earth ions and Zn2SiO4
                      was observed, the very fast response makes the materials an
                      interesting choice for scintillation devices.},
