Figure 2. SEM images (A) and (B) and TEM image (C) display the co-existence of large (4~5 µm) and small (~0.5 µm) particle sizes of ZnS:Ag,Mn phosphors. Image (D) is an EDS spectrum measured on a small particle shown in the image (C). EDS: Energy dispersive X-ray spectroscopy; SEM: scanning electron microscopy; TEM: transmission electron microscopy.
