## Abstract We study the propagation of exciton‐polaritons through bulk ZnO using time‐resolved photoluminescence (PL) complemented by time‐of‐flight measurements of laser pulses. When the photon energy approaches donor bound exciton resonances, substantial time delays in PL light propagation are o
