Mn-doped CdSSeTe-ZnS superlattices (SLs) have been prepared by a hot w
all technique, and double insulating electroluminescent devices of the
SL layers have been prepared. The red shifted emission of 10-100 nm w
avelength have been observed due to the high strain by the large latti
ce mismatches (7.5-16%). The characteristics of the most shifted one (
CdTe-ZnS case) are the peak photon wavelength of 675 nm and the lumina
nce of 450 cd/M2.
