Abstract

Heterostructures based on ZnO nanorods and CsPbBr3 nanocrystals were investigated for their potential as semiconductor SERS substrates. We found that ZnO morphology governs the efficiency of interfacial energy transfer, leading to enhanced photoluminescence under 390 nm excitation and a noticeable reduction of the bandgap in the composites. Raman analysis revealed a pronounced intensity enhancement and the emergence of low-frequency CsPbBr3 modes isolated via Gaussian deconvolution, which confirms the SERS-like behavior of the hybrid structures. Our results highlight the strong prospects of ZnO/CsPbBr3 heterostructures for sensing and optoelectronic applications.
