THE LUMINESCENCE PROPERTIES Zn/Mn PYROPHOSPHATE
2015
V. Boyko, O. Gomenyuk, S. Nedilko
Luminescence properties of two valence metals anhydrous double phosphates Zn2-хMnхP2O7 (x = 0 ÷ 2) have been investigated. It was shown that Mn2+ ions form three types of the emission centers where Mn2+ ion can be located, first in the regular octahedral oxygen environment, second, in defect octahedra that has oxygen vacancy, and third, – in the tetrahedral oxygen environment. Red emission with peak position near 690–700 nm is accompanied with the first type of luminescence centers; second type of the centers determines other red luminescence (peak position is near 730 nm) and third type of the centers originates “green” emission (peak position is about 450–470 nm).
