One-dimensional heterostructural metallodielectric photonic band gap material for the modification of emission spectrum of BaF2 scintillator

Abstract

Photonic bands in two-dimensional metallodielectric photonic crystals composed of metal coated cylinders J. Appl. Phys. 106, 033101 (2009); 10.1063/1.3183934 Bragg attenuation length in metallo-dielectric photonic band gap materialsOne-dimensional metallodielectric heterostructural photonic band gap (PBG) material is designed to reach high transmittance band in short wavelength, broad and deep forbidden band in long wavelength, especially sharp cutoff edge between the transmission and forbidden bands. The designed PBG material is applied to modify the emission spectrum of a BaF 2 scintillator and is proved to be adequate to suppress the slow component of the scintillation light. The suppression ratio of the slow to the fast component reaches 28 dB with a tolerable attenuation of the fast component.

Optical properties of a periodic one-dimensional metallic-organic photonic crystal

“…Light weight, reduced size, easier fabrication and lower costs are some of the reasons for the great interest in one-dimensional metallic-dielectric photonic crystals (MDPC) in recent years [1][2][3][4][5][6][7][8][9]. Researches on MDPCs are included in the microwave, millimetrewave and far-infrared frequencies and in the visible range.…”
