title: Green Upconversion Emissions in Er³⁺/Yb³⁺ Co-Doped CaMoO₄Prepared by Microwave-Assisted Metathetic Method.
abstract: In this study Er³⁺ doped CaMoO₄ (CaMoO₄:Er³⁺), and Er³⁺/Yb³⁺-co-doped CaMoO₄ (CaMoO₄:Er³⁺Yb³⁺) nanoparticles have been synthesized by the microwave-assisted metathetic method. Er³⁺/Yb³⁺ co-doped CaMoO₄ nanoparticles sintered at 600 °C showed the strongest photoluminescence intensity, and crystallized well. At the excitation of 980 nm, the CaMoO₄ nanoparticles show the strongest green emission at the 520 nm and 550 nm emission bands. Moreover, the green light produced has a better color purity.
