ROLE OF LITHIUM IN THE FORMATION OF EXCITON LUMINESCENCE OF ZINC OXIDE
Abstract
A detailed interpretation of exciton lines caused by the presence of a lithium impurity in ZnO crystals (T = 4.2 K) was carried out: the 368.5 nm line is caused by the radiative recombination of excitons bound on neutral donor states Liix; the 371.2 nm line is caused by the same process, but occurring simultaneously with the transition of the donor to the excited state; the 368.2 nm line occurs when excitons bound on ionized Lii+ states emit, and finally, line 369.7 nm is the emission of excitons bound on acceptor complexes of the form (Zni + LiZn| ), (InZn+ LiZn| ), (Lii + LiZn| ), etc. The measurement data also made it possible to calculate the ionization energy of shallow donors Liix:Ed = 0.033 eV. Thus, a method for exciton spectroscopy of lithium states affecting the optical and electrophysical characteristics of zinc oxide has been developed.
