AI Article Synopsis

  • WMS has a unique flower- or dendritic-like structure with adjustable pore sizes and a highly organized 3D pore system.
  • A method was developed to encapsulate semiconductor nanoparticles, specifically zinc oxide and holmium-doped zinc oxide, within the WMS during its creation.
  • Various characterization techniques such as TEM, SEM, UV-vis spectroscopy, and others were used to analyze the properties of the ZnO@WMS and Ho:ZnO@WMS particles.

Article Abstract

Wrinkled mesoporous silica (WMS) has a flower- or dendritic-like morphology, tunable pore size, and highly ordered and accessible three-dimensional (3D) pore structures. In this research, a method to encapsulate semiconductor nanoparticles in the core of the wrinkled mesoporous silica during synthesis is described. Highly uniform zinc oxide and holmium-doped zinc oxide nanoparticles have been synthesized by a sonochemical method. Zinc oxide and holmium-doped zinc oxide nanoparticles have been encapsulated in wrinkled mesoporous silica during synthesis. The ZnO@WMS and Ho:ZnO@WMS particles have been characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), UV-vis spectroscopy, fluorescence, dynamic light scattering (DLS), confocal microscopy, and X-ray diffraction (XRD).
