Abstract
In this work, a series of ZnxMg1.99-xSnO4:0.01Mn2+ (x = 0, 0.01, 0.02, 0.03, 0.04) green long afterglow phosphors are prepared by high-temperature solid-phase reaction. The photoluminescence and long afterglow performance of host material doped with Zn2+ are investigated. The results show that the emission peak of Mn2+ is red-shifted by 5 nm with increasing Zn2+ concentration. Zn0.03Mg1.96SnO4:0.01Mn2+ phosphor has the strongest green luminescence intensity with the chromaticity coordinates of (0.085 7, 0.608 3) under 270 nm, and Zn0.01Mg1.98SnO4:0.01Mn2+ phosphor has superior long afterglow performance with average lifetime of 102.41s. The afterglow decay and thermoluminescence curve of phosphor are used to explain the mechanism of long afterglow luminescence. Meanwhile, the afterglow intensity distribution of each pixel in Zn0.01Mg1.98SnO4:0.01Mn2+ coating samples is carried out by hyperspectral imaging, and the optimal luminescence intensity and uniformity of the sample are obtained at a phosphor/epoxy mass ratio of 0.002 5. Therefore, Zn0.01Mg1.98SnO4:0.01Mn2+ can be a potential candidate of novel long afterglow phosphors, and hyperspectral imaging also provides new research approaches for the rational proportioning of luminescent materials.
