Nanoparticles (NPs) synthesized via a facile sonochemical route showed excellent assembly of BaTiO₃:Eu³⁺@SiO₂ superstructures (SS) using CTAB as a surfactant. Crystallite size, phase, surface science, and core–shell confirmation were determined through advanced characterization techniques. Experimental parameters like pH, temperature, and surfactant concentration were varied and resulted in SS with high surface modifications, and the possible mechanisms for the same are reported. Scanning electron microscopy images revealed broomlike structures, and various experimental parameters resulting in them dissolving into freestanding sticks are discussed. CIE chromaticity coordinates were in the range of the orange-red to pure red. Drawbacks associated with the commercial powder dusting method for visualizing dormant fingerprint (DFP), namely, high background scattering and high autofluorescence of the substrate material, were improved with the help of the prepared SS as a dusting powder. Visualization of DFPs and sweat pores on various kinds of surfaces was studied effectively and systematically and revealed the well-defined first-, second-, and third-level ridge particulars with high contrast, high selectivity, and low background interference. These results suggest different strategies to engineer SS and highlights a method to obtain high-resolution DFPs. The prepared compounds are also utilized in antiforging ink and optoelectronics applications.
