Strongly enhanced luminescence of SrAlO:Mn phosphor by co-doping B and Na ions with red emission for plant growth LEDs.

Development of a more cost-effective radiation source for use in plant-growing facilities would be of significant benefit for commercial crop production applications. A series of co-doped B and Na ions SrAlO:Mn inorganic luminescence materials which can be used for plant growth were successfully synthesized through a conventional high-temperature solid-state reaction. Powder X-ray diffraction was used to confirm the crystal structure and phase purity of the obtained samples.
