The CuInSe2–CuGaSe2–2CdSe system and crystal growth of the γ-solid solutions

The CuGaSe2–CuInSe2–2CdS system and single crystal growth of the γ-phase

“…The reported phase diagram of the CuInSe 2 -CuGaSe 2 system [23] takes into account the peritectic type of the CuGaSe 2 formation. This phase diagram in the CuGaSe 2 -rich part at liquidus temperatures contains several fields that correspond to the primary and secondary crystallization of the g 0 -phase, which takes part in the peritectic reaction yielding CuGaSe 2 in the system Cu 2 Se-Ga 2 Se 3 .…”

A continuous range of the chalcopyrite solid solutions based on LT-modifications of CuInSe 2 and CuGaSe 2 exists in the system at 870 K [23][24][25]. Single crystals of the CuGa x In 1 À x Se 2 solid solutions have the chalcopyrite structure and are of the p-type [25].…”

“…The pseudo-quaternary reciprocal system CuIn, CuGa, Cd99S, Se embraces all particular cases. It can be presented geometrically as a triangular prism bounded by reciprocal systems CuInS 2 + 2CdSe#CuInSe 2 + 2CdS [18], CuGaS 2 + 2CdSe#CuGaSe 2 +2CdS [20], CuGaS 2 + CuInSe 2 # CuGaSe 2 +CuInS 2 [21] and two pseudo-ternary systems CuInS 2 -CuGaS 2 -2CdS [22] and CuInSe 2 -CuGaSe 2 -2CdSe [23]. Some g-solid solutions based on the quaternary compound CuCd 2 GaSe 4 with the sphalerite structure were found in the CuGaSe 2 +2CdS#CuGaS 2 + 2CdSe system [20], as well as in the CuInS 2 -CuGaS 2 -2CdS system [22].…”

Considerable g-solid solutions also exist in the pseudo-ternary system CuGaSe 2 -CuInSe 2 -2CdSe at 870 K [23]. The band gap energy of the g-solid solutions along the 'CuCd 2 InSe 4 '-CuCd 2 GaSe 4 section changes from 1.05 to $1.30 eV.…”

Synthesis and luminescence studies of CdSrS nanostructures

“…In recent years, hybrid materials have received growing research interests, since they usually provide a new functional hybrid with synergistic or complementary activity between each constituent, which are not available from their single components, and can provide novel or enhanced properties for various applications [1,2]. Especially, sulfide hybrid materials have attracted considerable attention because of their unique luminescence, magnetic, electrical and photocatalytic properties [3][4][5][6].…”
