Upconversion multicolor tuning: Red to green emission from Y2O3:Er, Yb nanoparticles by calcination

(author unknown)



Qipeng Lu, Yanbing Hou, and Aiwei Tang et al.

In this paper, we report the color tuning of Er and Yb codoped Y2O3 upconversion materials by calcination within a fixed doping concentration under the excitation of 980 nm semiconductor laser diode. By introducing the defects through use of a surfactant (cetyltrimethylammonium bromide) and removi ... [Appl. Phys. Lett. 102, 233103 (2013)] published Tue Jun 11, 2013.
