Identification of fine particles emitting fluorescence in toner

  • Summary

EM2020-01E

In toner, there are a variety of color particles to produce vivid colors. Therefore, when irradiating specific light wavelengths to toner particles by using a light microscope (LM), fluorescence characteristic to each color particle can be observed. Using the "on chip CLEM" which enables overlaying images with high precision, we were able to easily identify fine particles that emitted fluorescence and perform detailed TEM observations.
