Upconversion for White Light Generation by a Single Compound
A new multiphoton upconversion process for rare earth oxide powders is reported, using infrared laser diodes. In vacuum, multiphoton excitation produces intense upconversion emission in the visible spectral range, and Tm2O3 or Yb2O3 achieves pure white upconversion using 808 or 975 nm excitation, re...

| Zusammenfassung: | A new multiphoton upconversion process for rare earth oxide powders is reported, using infrared laser diodes. In vacuum, multiphoton excitation produces intense upconversion emission in the visible spectral range, and Tm2O3 or Yb2O3 achieves pure white upconversion using 808 or 975 nm excitation, respectively. |
