闪烁膜在辐射探测中起着重要的作用。提高光输出和控制发射方向对实际应用至关重要。为了增强Lu2SiO5:Ce3+闪烁薄膜的宽带定向发光，在薄膜表面沉积了一种特殊的光子晶体结构，以提供多个导模共振。结构可根据应用要求进行设计。通过数值模拟分析了增强效果。总的来说，该方法可用于需要定向发射的辐射检测。
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.
