Here, it is demonstrated that freestanding oxide membranes supply a reconfigurable platform for nano-photonics based on propagating surface phonon polaritons. Infrared near-field imaging and spectroscopy enabled by a tunable ultrafast laser are applied to study pristine nano-thick SrTiO<sub>3</sub> membranes prepared by hybrid molecular beam epitaxy. As predicted by coupled mode theory, it is found that strong coupling of interfacial polaritons realizes symmetric and antisymmetric hybridized modes with simultaneously tunable negative and positive group velocities. By resolving reflection of these propagating modes from membrane edges, defects, and substrate structures, their dispersion is quantified with position-resolved nano-spectroscopy. Remarkably, polariton negative dispersion is found to be both robust and tunable through choice of membrane dielectric environment and thickness, and proposes a novel design for in-plane Veselago lensing harnessing this control.

In this study, focus is placed on hypervalent gallium azobenzene complexes with variable coordination motifs because of a wide accessible space around gallium. The six-, five-, and four-coordinated gallium azobenzene complexes are isolated with pyridine ligands, and it is observed that the coordination of pyridine can dynamically change in the solution. Interestingly, the enhancement of the absolute fluorescence quantum yields is observed by the suppressing structural relaxation as increasing the coordination number. Furthermore, it is found that the emission efficiency is enhanced as increasing donor number which represents the strength of Lewis basicity. Finally, it is demonstrated that the filter paper soaked by the synthesized gallium complex is prepared, and it worked as a turn-on luminescent sensor to easily visualize strength of Lewis basicity of solvents by simply dropping the solvent on the paper.

Experimental results, supported by particle-in-cell simulations, reveal that electron emission via Fowler–Nordheim tunneling can be dynamically steered by varying the applied bias. A positive bias suppresses emission by attracting electrons to the bias arms, while a negative bias repels them, allowing trajectory control and the emergence of new emission features.

The anisotropic excitonic component in the cavity results in strongly polarization-dependent light-matter interaction and in increased Rabi-energies.
