Abstract

To develop a white light-emitting diode (LED) phosphor with a better performance, we will make an Er^3 + / Tm^3 + / Yb^3 + tridoped ZrO₂ / WO₃ composite nanophosphor through the sol–gel method. Using a 975-nm laser diode, we analyze the upconversion luminescence performance of the sample. The result shows that the Er^3 + / Tm^3 + / Yb^3 + tridoped sample can emit strong white light and its color temperature is adjustable. The study helps to explore efficient, complex nanophosphors for white LEDs.
