## Abstract Tm^3+^βdoped Y~2~O~3~ nanocrystals were prepared via hydrothermal conditions at high autogenous pressure (ca. 40 MPa) using batch reactors at 220 and 250 Β°C for very short periods of reaction time (10 min). The asβprepared materials were identified as Y(OH)~3~ nanoparticles. The precurs
Chalcohalide glasses of the system 100y((GeS 2 ) 80 (Sb 2 S 3 ) 20-x (PbHal 2 ) x )β’yPr 2 S 3 , where Hal is I or Cl, x = 2 or 5, y = 0.01 or 0.1, were prepared by direct synthesis from high purity Ge, Sb, S, Pr and PbCl 2 or PbI 2 . The prepared glasses were stable and homogeneous. Absorption spect
