Abstract
⺠Charge-transfer absorptions from O2â to Fe+ were revealed at 4.7, 5.8 and 6.5 eV. ⺠From reflection spectrum at 7 K the bandgap Eg was estimated as 7.8-8.2 eV. ⺠Intrinsic PL at 3.28 eV originates from annihilation of self-trapped exciton. ⺠Strong PL band at 1.72 eV originates from a radiative transition in Fe3+ ion. ⺠PL bands at 2.68 and 3.54 eV originate from Fe3+ associated with lattice defects.
