Ca14Zn6Al10O35:Eu3+, Nd3+ phosphors were synthesized using precursors impregnated with starch in aqueous metal salt solutions of Ca, Zn, Al, Nd, and Eu. As a result of measuring the photo luminescence of the synthesized Ca14Zn6Al10O35:Eu3+, Nd3+ phosphor powder, light in a wavelength range of 650-780 nm was emitted. The phosphor emitting light in this wavelength range can be applied to a red light source in a plant factory. The surface structure, components, and crystallinity were investigated by scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) X-ray diffraction analysis(XRD). As a result of XRD analysis, it was confirmed that pure Ca14Zn6Al10O35:Eu3+, Nd3+ phosphor having a single phase was synthesized. As a result of EDS and SEM analysis, the synthesized Ca14Zn6Al10O35:Eu3+, Nd3+ phosphor powder contained Eu and Nd ions, which were used as activators, and the particle size of the powder was uniform.
