Wi. Lee et Yr. Do, CRYSTAL-GROWTH AND CHARACTERIZATION OF THE SOLID-SOLUTION (ZNSE)(1-X)(CUMSE(2))(2) (M=AL, GA, OR IN), Bulletin of the Korean Chemical Society, 16(7), 1995, pp. 588-591
Single crystals of (ZnSe)(1-x)(CuMSe(2))(x) (M=Al, Ga, or In) were gro
wn by chemical vapor transport technique. Powdered polycrystalline sam
ples of (ZnSe)(1-x)(CuMSe(2))(x) (M=Al, Ga, or In) were also prepared
by the direct combination of the elements. The chemical composition of
these single crystals was determined by comparing their lattice param
eters with those of the standard polycrystalline samples. The IR trans
mission range of single crystals of (ZnSe)(1-x)(CuMSe(2))(x) (M=Al, Ga
, or In) is sightly narrower than that observed for pure ZnSe. However
, these materials still show good transmission in the long-wavelength
IR range. The addition of small amounts of CuMSe(2) (M=Al, Ga, or In)
considerably increases the hardness of ZnSe.
