Abstract: Artificial light sources such as phosphor-converted light-emitting diodes (pcLEDs) are very much crucial requirement for plant growth in a controlled environment. The Mg, Mn co-doped La2LiSbO6 phosphors are prepared using solid state reaction route. The phase purity of the prepared samples is analyzed qualitatively and photoluminescence characteristics are investigated. The PL emission was found to be at around 712 nm, a deep red emission lies in the Photosynthetically active radiation (PAR) region under 323 nm UV excitation. Spectroscopic properties of Bi3+ sensitized Mg, Mn co-doped La2LiSbO6 phosphors are investigated and the PL intensity is found to be quenched thereby indicating the ineffective energy transfer of Bi3+ sensitizers to Mn4+. The Mg, Mn co-doped La2LiSbO6 phosphors can be suitably tuned to design phosphors converted plant growth LEDs that will be useful in smart agriculture.
