摘要: Abstract Orthorhombic magnesium germenate (Mg 2 GeO 4 ) doped with manganese was synthesized by solid-state reaction technique. A broad red emission a peak at 653 nm observed independent of excitation wavelength. The effect Zn incorporation on structural and optical properties is investigated, keeping the concentration Mn fixed 2 at.%. XRD DRS analysis samples reveal formation solid solution up to x = 0.10 beyond which phase segregation occurs. Formation sub-band gap for decreased doping. Both green above = 0.10. Red attributed T 1 → 6 transition 2+ Mg site in from . PLE found be red-shifted
