Metal-organic frameworks (MOFs) are superior for multiple applications including drug delivery, sensing, and gas storage because of their tunable physiochemical properties and fascinating architectures. Optoelectronic application of MOFs is difficult because of their porous geometry and conductivity issues. Recently, a few optoelectronic devices have been fabricated by a suitable design of integrating MOFs with other materials.

- - Multifunctional lanthanide-doped upconversion nanoparticles (UCNPs) are making strides in flexible optoelectronics and biomedical fields, specifically through the development of nanocomposites that can achieve lasing under low power conditions.
- - A new design, featuring gold sandwich UCNP nanocomposites, shows promising results in lasing with a threshold as low as ~0.06 kW cm, aided by the unique energy-level characteristics of lanthanides and electromagnetic effects from localized surface plasmon resonance.
- - These nanocomposites demonstrate potential applications in bioimaging and antibacterial treatments, specifically through photothermal therapy, showcasing their versatility and effectiveness in biological contexts.
Article Synopsis
- Plasmonic materials can manipulate light effectively, but they face challenges like propagation loss and limited resonance bandwidth, hindering broader applications.
- The study introduces a new nanoscale core-shell hyperbolic structure, which enhances electron oscillation and density of states, enabling stronger localized electromagnetic waves and a significant out-coupling effect.
- This innovative structure not only minimizes energy loss but also achieves an ultra-low threshold for stimulated emission, potentially improving technologies like solar cells, LEDs, and advanced imaging systems for medical research.
Aims: The purposes of this study were to describe the visual outcome of highly myopic eyes undergoing cataract surgery, to investigate associated risk factors for poor postoperative vision, and to assess postoperative complication frequency among the prevalent myopic Taiwanese population.
Methods: We conducted a retrospective, noncomparative case series study at the Department of Ophthalmology, Zhongxing Branch, Taipei City Hospital, Taiwan. High myopia was defined as axial length of 26.
