M2GeO4:Mn5+(M = Ca, Sr, Ba) phosphors have been synthesized by solid-state reaction method. The strongest PL intensity under 600 nm excitation is observed from the Ca2GeO4 host. Its PL integrated intensity is stronger by 6.7 times than that of the Ca10(PO4)6(OH)2:Mn5+ nanoparticle phosphor synthesized by liquid-phase reaction method.
