QUIJANO, Natalia; GAONA J., Sonia  and  RAMIREZ S., Alfonso. Synthesis and characterization of Pr₂S₃ binary compound. Ciencia en Desarrollo [online]. 2018, vol.9, n.2, pp.95-98. ISSN 0121-7488.

In the current work it is shown that the synthesis method that consists in direct reaction of praseodymium and sulfur in its elemental form, using heat as a treatment, with relatively low temperatures and reaction time of one week, allows the preparation of Pr2S3 compound, with a purity of about 92%. The respective characterization of resultant materials was carried out using powder XRD, where by it was determined that the thermal treatment used, effectively leads to the binary sulfide of interest, a compound known to be semiconductor.

Keywords : praseodymium sulfide; thermal treatment; semiconductor.
