Cathodoluminescence (CL) microscopy has emerged as a powerful tool for investigating the optical properties of materials at the nanoscale, offering unique insights into the behavior of photonic and plasmonic materials under electron excitation. We introduce an atlas of bulk CL spectra and intensity for a broad range of materials used in photonics and plasmonics. Through a combination of experimental CL microscopy and Monte Carlo simulations, we characterize spectra and intensity of coherent and incoherent CL, electron penetration depth and energy deposition, offering a foundational reference for interpreting CL signals and understanding material behavior under electron excitation. Our atlas captures CL signals across a wide range of materials, offering valuable insight into intrinsic emission properties for informed material selection and device design in photonics and plasmonics.
阴极发光(CL)显微镜已成为研究纳米尺度材料光学特性的强大工具,为深入了解光子和等离子体材料在电子激发下的行为提供了独特视角。我们介绍了一个用于光子学和等离子体学的广泛材料的体CL光谱和强度图谱。通过结合实验CL显微镜和蒙特卡罗模拟,我们对相干和非相干CL的光谱和强度、电子穿透深度和能量沉积进行了表征,为解释CL信号和理解电子激发下的材料行为提供了基础参考。我们的图谱涵盖了广泛材料的CL信号,为光子学和等离子体学中明智的材料选择和器件设计的固有发射特性提供了有价值的见解。
