The formation of solid solution series Cs(1-x)M(x)GaQ(2)-mC64 (M = K, Rb; Q = S, Se; x = 0-1) was studied by X-ray diffraction and spectroscopic methods, revealing a complete miscibility of CsGaQ(2)-mC64 with RbGaQ(2) and KGaSe2, and a large miscibility gap with KGaS2. All solid solution members exhibit similar Raman spectra, indicating the covalent Ga-Q bonding character. The similar optical ...
