A hybrid-sponge nanostructure deserves special interest because of the use of a plasmon nanosponge as an amplification element of an optical pump that excites the photoluminescence semiconductor. A feature of the structure is the direct location of the semiconductor in the pores of the plasmon sponge, where the localization of the exciting radiation occurs directly. In this work, we study an application of laser annealing for the photoluminescence tuning of the hybrid metal-dielectric sponge nanostructure. We demonstrate that time of laser annealing has influence on photoluminescence spectra as well as dark-field signal from the objects. We believe that applied method can be utilized as effective tool for optical properties tuning of hybrid nanosponges for the development of reconfigurable nanoscale sources of broadband radiation.
