© 2016, Chiang Mai Journal of Science. All Rights Reserved. n-type CdS 0.9 Se 0.1 powder was produced by mixing and annealing of CdS and Se powders that were prepared by a reflux method using Cd(CH 3 CO) 2 ·2H 2 O, thiourea and ethylene glycol, and by a solution method using SeO 2 , ethylene glycol and NaBH 4 , respectively. The product was supposed to be crystalline CdS 0.9 Se 0.1 powder from simulation of X-ray diffraction pattern using CaRine 3.1 program and JCPDS card of CdS (space group P63mc). Analytical electron microscopy revealed that Cd, S and Se atoms were homogeneously distributed in the powder, which was composed of particles as fine as a few ten nm and in a single crystalline phase, supporting the formation of CdS 0.9 Se 0.1 . This CdS 0.9 Se 0.1 powder is expected to be used as n-type thermoelectric materials.
