Abstract
Anthracene fibers are grown inside a microstructured quartz matrix to form a multicore optical fiber for X-ray detection. A modified fiber growth method for single crystal anthracene from the melt via the Bridgman-Stockbarger technique is presented. The anthracene fiber is characterized by using spectrophotometry, Raman spectroscopy, and X-ray diffraction. These results show the anthracene grown in fiber has high purity and a crystal structure similar to anthracene grown from liquid, vapor, and melt techniques. As an X-ray detector, the output is 12%–16% efficient between the energy ranges of 40 and 10 keV. The effect of materials and fiber processing are discussed.

Raman active symmetry and agree with theoretical wavenumber calculations and previous experimental relative intensity measurements [30,33]. These data demonstrate that the anthracene fiber has high purity and the molecular structure is similar to that of anthracene crystal grown from solution
Summary
Anthracene is an organic semiconductor material that is used as a scintillator for ionizing radiation detection [1,2,3,4]. The addition of quantum dots, carbon nanotubes, chemical coatings and liquids into microstructured optical fiber (MOF) provides various sensors for temperature, chemical, and X-ray detection [14,15,16,17,18,19,20]. These filled MOF devices operate based on various principles including fluorescence, absorption, and refraction index variations. This paper presents improvements in multicore organic single crystal anthracene fibers of a few microns in diameter for X-ray detection. The benefits of anthracene fibers integrated with the quartz MOF include increased photon collection, ease of handling due to the quartz support, enhanced functional reliability and flaw tolerance from multiple fibers in the quartz
