为了准确测量纳米颗粒的尺寸，依据透射电子显微镜拍摄的纳米颗粒图像，提出了一种基于U-Net卷积神经网络的颗粒自动分割方法。将U-Net部分网络结构与批量归一化层相结合，减弱了网络对初始化的依赖，提升了训练速度。对纳米颗粒图像进行半隐式偏微分方程滤波以增强图像边缘信息，利用改进的U-Net网络训练纳米颗粒个体分割模型，得到了分割结果。研究结果表明，所提方法能准确分割出图像中的纳米颗粒，对边缘模糊和强度不均的纳米颗粒的分割效果提升显著。

开发一种新型TiO2纳米线阵列干涉传感器。首先,通过水热合成法在FTO导电玻璃表面制备了TiO2纳米线阵列薄膜。然后,以此复合结构作为传感芯片,利用Kretschmann棱镜耦合结构,构建了基于Kretschmann结构的波长调制型薄膜干涉传感器。最后,以氯化钠水溶液为待测液体介质研究了该传感器对环境介质折射率的灵敏性能。结果表明:该传感器对1.333 5~1.360 4范围内的折射率有很好的响应。TM模式下,在0~3%与3~15%浓度范围内,氯化钠浓度与该传感器的反射光强度分别呈现了良好的线性关系。TE模式下,在0~3%浓度范围内,氯化钠浓度与吸收强度存在良好的线性关系,而波长基本不变;而在3~15%浓度范围内,随着氯化钠浓度的增加,波长逐渐红移,氯化钠浓度与波长也具有良好的线性关系。

This paper reviews the progress on nano-aperture vertical-cavity surface-emitting lasers (VCSELs). The design, fabrication, and polarization control of nano-aperture VCSELs are reviewed. With the nano-aperture evolving from conventional circular and square aperture to unique C-shaped, H-shaped, I-shaped, and bowtie-shaped aperture, both the near-field intensity and near-field beam confinement from nano-aperture VCSELs are significantly improved. As a high-intensity compact light source with sub-

We have seen a lot of unique features off vertical cavity surface emitting lasers (VCSELs), such as low power consumption, wafer-level testing, small packaging capability, and so on. The market of VCSELs has been growing up rapidly in recent years and they are now the key devices in local area networks using multi-mode optical fibers. In addition, new functions on VCSELs have been demonstrated. In this paper, the recent advances of VCSEL photonics will be reviewed, which include the wavelength e

In this letter, poly(vinylidene difluoride) (PVDF)/(Y0.97Eu0.03)2O3 rare-earth nanocomposites were prepared by a simple co-precipitation method, and their morphology, structure, and optical properties were investigated. The scanning electron microscope (SEM) images showed that the (Y0.97Eu0.03)2O3
