Processes of nanocrystalline phase formation in transparent yttrium oxyfluoride nano-glass-ceramics doped with neodymium ions are studied. An optimal heat treatment regime for a given glass composition is determined using differential thermal analysis (DTA). Glasses are heat-treated for 30, 60, and 120 min; the sizes of crystals are calculated, and the unit cell parameters are determined. The physicochemical and spectral properties of yttrium oxyfluoride glasses doped with neodymium ions, as well as of nano-glass-ceramics based on these glasses, are studied.
