Preparation and Luminescent Properties of Sr2MgAl22O36∶Mn4+ Phosphor-in-glass for Plant Growth LED
-PiG) was prepared by a two-step co-sintering technology at low temperature. The phase
composition and luminescent properties of PiG samples were investigated by X-ray diffraction(XRD)
scanning electron microscope(SEM)
excitation and photoluminescence spectra
fluorescence decay curve
etc
. Experimental results show that the phase and elemental composition of SMA∶Mn
4+
phosphor were well preserved after forming PiG. Under 328 nm excitation
PiG samples with different SAM∶Mn
4+
content all showed strong emission band peaked at 661 nm due to

ions. The emission spectrum of SMA∶Mn
4+
-PiG well matches absorption spectra of plant phytochromes. With the increase of phosphor content
the photoluminescence intensity of SAM∶Mn
4+
-PiG gradually increases. Internal quantum efficiency(IQE) and external quantum efficiency(EQE) of 15% SMA∶Mn
4+
-PiG samples are 26% and 20%
respectively
which are lower than 59% and 40% of SMA∶Mn
4+
phosphor. Compared with SMA∶Mn
4+
phosphor
absorption efficiency and thermal stability of SAM∶Mn
4+
-PiG are slightly enhanced. With packaging with high-power UV chip
SMA∶Mn
4+
-PiG red LED device exhibits high electroluminescence intensity
and the highest value is measured at 100 mA.
