Fig. 2: Microstructure of the bulk Mg2Al4Si5O18:Eu2+ red phosphor.
From: Glass crystallization making red phosphor for high-power warm white lighting
Digital photographs the crystallized composite phosphor with a thickness of 0.4 mm taken under a daylight and b blue light. c Low magnification TEM image of the phosphor particle, the inset is the corresponding selected area electron diffraction (SAED) pattern. d High-resolution TEM (HRTEM) pattern. e Corresponding intensity profile of d across image marked by the dashed green box were obtained. f Corresponding FFT image. g, h HAADF-STEM image and the Energy dispersive X-ray (EDX) mapping of Si, Mg, Al, O, and Eu elements
