In this work, we propose a method to control spontaneous emission in a double-V-type quantum emitter near a plasmonic nanostructure using optical excitation with vortex beams. By leveraging the spatial and phase variations of the vortex beams, a spatially dependent interference and coherence of the upper energy states is induced, leading to an altered emission spectrum. The study reveals phenomena such as emission peak narrowing and merging, along with pattern conversion and redistribution in the transverse plane. Importantly, this method allows for remote distance control of spontaneous emission by tuning the separation between the quantum emitter and the plasmonic nanostructure, offering a new way to manipulate emission properties in hybrid quantum-plasmonic systems. This approach could find applications in quantum information processing and tunable nanoscale photonic devices.
