Effects of Impurity Doping on the Luminescence

Mn4+ activated LaMgAl11O19 (LMA/Mn4+) with red emitting phosphor was obtained by sintering under air conditioning. The X-ray diffraction pattern Rietveld refinement results reveal that three six-fold coordinated Al sites are substituted by Mn4+ ions. Furthermore, the chemical valence state of manganese in the LMA host was further confirmed through X-ray photoelectron spectroscopy (XPS) (PDF) High efficiency Mn4+ doped Sr2MgAl22O 36 red The optimized red emitting Sr2MgAl22O 36:Mn4+ phosphor exhibits high quantum efficiency (QE) of 80%, fluorescence lifetime of 1.25 ms and the Commission International de I'Eclairage (CIE)

Microsized Red Luminescent MgAl 2 O 4:Mn 4+ Single

The photoluminescence property was studied at various temperatures, and Mg Al anti-site disorder induced luminescence broadening was discussed. The Mn 4+ 2 E g 4 A 2g transition in MgAl 2 O 4 shows a quite short luminescence wavelength peaking at 651 nm and ultrabroadband emission extending to 850 nm. The luminescence is relatively robust against thermal effect with relatively high
