A spiropyran-based X-ray sensitive fiber

Area of Science:

• Materials Science
• Optics and Photonics
• Medical Imaging

Background:

• X-ray imaging is crucial in diagnostics.
• Developing novel materials for enhanced X-ray visualization is an ongoing research area.
• Reversible imaging techniques can reduce radiation exposure and material waste.

Purpose of the Study:

• To investigate the potential of a novel poly-(l-lactic acid) composite fiber for visualizing X-ray radiation.
• To incorporate photostimulable phosphor (PSP) particles and a photochromic dye into the fiber for imaging applications.
• To explore the feasibility of reversible X-ray imaging using this composite material.

Main Methods:

• Fabrication of a poly-(l-lactic acid) (PLLA) composite fiber with an average diameter of 150 μm.
• Incorporation of barium fluorochloride doped with europium(II) (BaFCl:Eu(2+)) as photostimulable phosphor particles.
• Dyeing the composite fiber with a photochromic spiropyran dye (1,3,3-trimethylindolino-6'-nitrobenzopyrylospiran) (6-nitro BIPS).

Main Results:

• Successful visualization of X-ray radiation using the developed composite fiber.
• Demonstration of the photostimulable properties of BaFCl:Eu(2+) particles within the PLLA matrix.
• Evidence of reversible imaging capabilities due to the photochromic spiropyran dye.

Conclusions:

• The PLLA composite fiber containing PSP particles and a photochromic dye is a promising material for X-ray visualization.
• This material offers potential for developing reversible X-ray imaging systems.
• Further research can optimize the material for improved imaging performance and broader applications.
