Kurzfassung:
Mg x Zn 1- x Si: Ho 3+ , Mg x Zn 1- x Se: Er 3+ , and Mg x Zn 1- x Se: Tm 3+ single crystals were grown by the closed-tube sublimation method. The single crystals crystallized into a zincblende structure at the composition x = 0.11 and a wurtzite structure at the composition x = 0.25, 0.32, and 0.41. The trivalent ions (Ho 3+ , Er 3+ , and Tm 3+ ) of the rare-earth elements Ho, Er, and Tm site in T d and C 3 v symmetries in the single crystals with zincblende and wurtzite structures, respectively. Sharp emission peaks appeared in the photoluminescence spectra of the single crystals. These emission peaks are identified to originate from the radiation recombination between the energy levels of the trivalent ions sited in T d and C 3 v symmetries.
