Synthesis and photoluminescence of Eu2+–Mg2+ co-doped γ-AlON phosphors

Luminescent properties of a novel Al10O3N8:Eu2+ phosphor by a mechanochemical activation route

“…6. This broad emission spectrum is due to the overlap of emission spectra of AlON, AlN: Eu 2+ and Al 10 O 3 N 8 :Eu 2+ [8,27], whose existences are also confirmed by XRD results in Fig. 1.…”

“…Among these (oxy)nitride luminescent materials, c-AlON based phosphors have gained great interests due to their optical transparency and high thermo-mechanical properties [5][6][7][8][9].…”

Insight the Luminescence Properties of AlON: Eu, Mg Phosphor under VUV Excitation

“…As one kind of oxynitride, γ-aluminum oxynitride with spinel structure (hereafter AlON) is well known as a transparent ceramic in the visible light range and it has superior mechanical properties both at room and high temperature [5], which makes AlON a promising host-lattice for doping transition or rare-earth luminescent ions [6,7,8,9]. In particular, when doped with Eu 2+ ions, AlON can be developed into an interesting blue-green luminescent material which exhibits a strong emission band centered at 470–500 nm under 310–330 nm light irradiation [10,11,12]. …”

Characterization and luminescence properties of AlON:Eu2+ phosphor for white-emitting-diode illumination

“…The new luminescent materials of Mn 2þ , Mg 2þ co-doped and rare-earth Eu 2þ , Er 3þ , Tm 3þ doped AlON (Refs. [16][17][18][19][20] have been prepared and characterized. Among these phosphors described above, AlON:Eu 2þ can emit intense blue light under 350-410 nm UV LED chip excitation.…”

“…Among these phosphors described above, AlON:Eu 2þ can emit intense blue light under 350-410 nm UV LED chip excitation. 17,20 However, for application in high power LED, the thermal stability and quantum efficiency of phosphor are the important issues to be considered, which have not been studied for AlON:Eu 2þ to date. In this work, the excitation and emission spectra of specimens at various temperatures are measured and analyzed, and the mechanism and site distribution of Eu 2þ in AlON are investigated.…”
