Strain‐Induced Optical and Molecular Transformations in Poly(Ethylene Terephthalate) Films for Organic Electronic Applications

Advanced Photonics Research, EarlyView.
This study explores how mechanical strain affects the optical and molecular properties of poly(ethylene terephthalate) (PET) films, crucial for flexible electronics. Using UV–Vis and Raman spectroscopy, it reveals strain‐induced changes in transparency and vibrational modes. Findings provide insights into optimizing PET‐based devices like organic solar

Nonlinear Optical Microscopy of Semiconductor–Metal Nanocavities

Advanced Photonics Research, EarlyView.
Three‐dimensional nonlinear optical microscopy is used to visualize GaAs–gold hybrid nanocavities. By carefully selecting the pump wavelength to position the harmonic generation at the nanopillar resonance, an enhanced contrast is observed in the nonlinear imaging.

Design and Characterization of Low‐Threshold InP Nanowire Photonic Crystal Surface‐Emitting Lasers

Advanced Photonics Research, EarlyView.
The lasing performance of nanowire (NW) photonic crystal surface‐emitting lasers (PCSELs) is highly sensitive to changes in the photonic crystal lattice constant and the NW diameter. This study systematically investigates the threshold power and the threshold gain for different PCSEL geometries.

Local Structure–Luminescence Correlation in Eu3+‐Doped Phosphors: A Comprehensive Review

Advanced Photonics Research, EarlyView.
This review discusses the correlation between local structure and the luminescent properties of Eu3+ ions, and also summarizes analytical methods for determining Eu3+ site occupancy. The luminescence properties of the phosphors are determined by the electronic configuration of the activator ions and are also affected by the coordinated environment of ...
