Carbon Dot Synthesis in CYTOP Optical Fiber Using IR Femtosecond Laser Direct Writing and Its Luminescence Properties

Luminescent carbon dots (CDs) were locally synthesized in the core of CYTOP fibers using IR femtosecond laser direct writing (FLDW), a one-step simple method serving as a post-treatment of the pristine fiber. This approach enables the creation of…

Optical properties of fs laser-created sphere inside CYTOP fiber by Mueller polarimetry

Optical elements embedded in an optical fiber can be used to shape and modulate the light transmitted within. We consistently observe, via Mueller polarimetry, that the optical properties of a femtosecond (fs) laser-created spherical cavity within a…

3D real-time single particle tracking using two-photon fluorescence from bright dye-based organic nanoparticles

This paper addresses the use of ultrabright dye-based fluorescent organic nanoparticles in a 3D single-particle tracking two-photon microscopy setup. The nanoparticles consist of an assembly of quadrupolar dyes, presenting a large two-photon…

Direct fabrication of rough gold nanoholes and investigation of their second-harmonic generation

Abstract In this study, we introduce a simple and cost-effective technique called one-photon absorption-based direct laser writing (OPA-based DLW) to directly fabricate noncentrosymmetric gold nanoholes (Au NHs). This technique relies on the…

LASU: An efficient and stable phthalocyanine dye with tolerable safety profile for self-disinfecting anti-COVID textiles activated by ambient light

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo…

Photobleaching Step Counting and Localization for Fluorescence Microscopy

Fluorescence microscopy is a fundamental tool for studying biological systems at the single-molecule level. In particular, photobleaching step patterns can provide valuable insights into molecule interactions. Several works have proposed an…
