![]() ![]() The photoluminescence properties of individual ZnO nanorods, grown by atmospheric pressure metalorganic chemical vapor deposition (APMOCV) and chemical bath deposition (CBD) are investigated by means of temperature dependent micro- PL. Holtz, Per-Olof Nigussa Urgessa, Zelalem Samuel Oluwafemi, Oluwatobi Reinhardt Botha, Johannes Khranovskyy, Volodymyr Yakimova, Rositza Karlsson, Fredrik Syed, Abdul S. International Nuclear Information System (INIS) The PL properties of individual ZnO nanorods can be of importance for their forthcoming application in future optoelectronics and photonics. The resulting room temperature DLE was a wide band located at 420-550 nm. ![]() It was observed that while APMOCVD ZnO nanorods possess a constant low signal of visible deep level emission with temperature, the ZnO nanorods grown by CBD revealed the thermal activation of deep level emission (DLE) after 130 K. The FX was found to dominate after 150 K for both samples. The temperature increase causes a red energy shift of the peaks and enhancement of the free excitonic emission (FX). It was found that the low temperature PL spectra are driven by neutral donor bound exciton emission DX, peaked at 3.359 and 3.363 eV for APMOCVD and CBD ZnO nanorods, respectively.
