    Notes: MgAl2Se4, MgAl2Se4:Er3+, CaAl2Se4, and CaAl2Se4:Er3+ single crystals were grown by the chemical transport reaction method. The single crystals had the direct energy band gap and their optical energy gaps were 3.286, 2.855, 3.823, and 3.525 eV for the MgAl2Se4, MgAl2Se4:Er3+, CaAl2Se4, and CaAl2Se4:Er3+ single crystals, respectively, at 13 K. Broad photoluminescence spectra peaked at 477 and 672 nm for the MgAl2Se4 single crystal and at 459 and 633 nm for the CaAl2Se4 single crystal were obtained. Sharp emission peaks due to the Er3+ ion in the MgAl2Se4:Er3+ and CaAl2Se4:Er3+ single crystals were observed. © 1999 American Institute of Physics.
