X-ray dose detector based on color changing of light-emitting polymer–metal complex hybrid material

We report on the design, fabrication and performance of a poly (2-methoxy-5(2′-ethylhexyloxy)-p-phenylenevinylene)/tris-(8-hydroxyquinoline)aluminum (MEH-PPV/Alq3) X-ray dose detector for improving safety for cancer patients shortly before radiation therapy. The detector consists of an inexpensive (

► Evaluation of high-energy X-ray dose radiation detector for improving safety for patients with cancer shortly before radiation therapy.
► A novel X-ray detector based on MEH-PPV/Alq3 which are rarely seen together.
► A strong correlation between the photoemission spectrum of Alq3 and the photoemission and absorption spectra of MEH-PPV degraded by radiation.
