摘要：

Scintillation films play an important role in radiation detection. Improved light output and control of emission directionality are critical for practical applications. To obtain enhancement of broadband directional luminescence from a Lu2SiO5: Ce3+ scintillation film, a special photonic crystal structure is deposited on the film surface to provide multiple guided-mode resonances. The structure can be designed according to the application requirements. Numerical simulations are performed to analyze the enhancement. Overall, this method could be used when directional emission is required for radiation detection. Published by AIP Publishing.
