Abstract
The merger of the absorption coefficient dispersion, retrieved from transmission by the modified Urbach rule introduced by Ullrich and Bouchenaki [Jpn. J. Appl. Phys. 30, L1285, 1991], with the extended Roosbroeck-Shockley relation reveals that the optical absorption in ZnO distinctively determines the photoluminescence lineshape. Additionally, the ab initio principles employed enable the accurate determination of the carrier lifetime without further specific probing techniques.

This work is closing the void: Employing the model of Ullrich and Bouchenaki,[10] the absorption dispersion of bulk ZnO is deduced from transmission measurements and, by use of this information, we demonstrate via the extended Roosbroeck–Shockley relation (RSR)[11,12,13] the intrinsic relationship between absorption and PL lineshape
