In this study, we developed active substrates consisting of Ag-decorated silicon nanowires on a Si substrate using a single-step Metal Assisted Chemical Etching (MACE) process, and evaluated their performance in the identification of low concentrations of Rhodamine 6G using surface-enhanced photoluminescence spectroscopy. Different structures with Ag-aggregates as well as Ag-dendrites were fabricated and studied depending on the etching parameters. Moreover, the addition of Au nanoparticles by simple drop-casting on the MACE-treated surfaces can enhance the photoluminescence significantly, and the structures have shown a Limit of Detection of Rhodamine 6G down to 10-12 M for the case of the Ag-dendrites enriched with Au nanoparticles.

- This study presents a method to improve energy level alignment and electron injection in organic light emitting diodes (OLEDs) using functionalized zinc porphyrin compounds as interlayers.
- The researchers focus on different configurations, molecular dipole moments, and terminal groups of the porphyrins to analyze their impact on optical properties and energy levels through various spectroscopy and measurements.
- The results show that incorporating these functionalized porphyrin interlayers enhances OLED performance significantly, achieving luminance levels an order of magnitude greater than standard devices without these modifications.
