Monodisperse micro-spherical Sr2-zMg1+yYzAl22-xO36∶xMn4+red phosphors
文献摘要：
With narrow red photoluminescence(PL)bands,tetravalent Mn4+doped phosphors show promising prospect in commercial application to effectively expand color gamut of phosphor converted LED dis-plays.Here,we report a type of Sr2-zMg1+yYzAl22-xO36∶xMn4+phosphors with regular cage-like micro-spherical morphologies.The micron size spherical precursors were synthesized with a propylene oxide(PO)driven fast sol-gel method.The cage-like spherical morphology is beneficial to efficiently trapping much incident light to enhance the PL of the phosphors.Being calcined at 1300℃,Sr2MgAl21.978O36∶0.022Mn4+only exhibits the internal quantum efficiency(IQE)of 24.91％.With the Mg2+-Mn4+codoping and Y3+/Sr2+substituting strategies,to fulfill charge balance and produce John-Teller distortion,IQE of Sr2-zMg1+yYzAl22-xO36∶xMn4+can be further improved up to 36.45％.The CIE color coordinates of Sr2-zMg1+yYzAl22-xO36∶xMn4+under near ultraviolet excitation can be stably fixed to(0.723,0.227)at deep red region.It thus finds a potential application as pc-LED display with much broader color gamut than that of the NTSC standard.Therefore,Sr2-zMg1+yYzAl22-xO36∶xMn4+micron size spheres can be employed as promising red phosphors for high performance LED displays.
