Highly Efficient Far-Red Emitting Mg₂₁Ca₄Na₄(PO₄)₁₈: Ce³⁺, Eu³⁺ Luminescent Glasses: A Novel Approach Towards Plant Cultivation Technologies

One of the exciting developments in contemporary luminescence research is the development of rare earth triggered luminescent glasses, which are a type of lanthanide activated luminous material. For the first time, Ce³⁺, Eu³⁺ activated/co-activated Mg₂₁Ca₄Na₄(PO₄)₁₈ orthophosphate glasses have been synthesized using the proposed work's melt quenching technique. The proposed glass sample's XRD pattern has an amorphous character, although its most prominent peak matches data from the Mg₂₁Ca₄Na₄(PO₄)₁₈ standard ICSD database. FT-IR analysis was used to analyze the proposed glass sample's vibrational characteristics. Co-activated Mg₂₁Ca₄Na₄(PO₄)₁₈ glass exhibits large emission peaks under UV excitations that cover the far red area during a photoluminescence examination. These outcomes demonstrate the proposed sample's value in applications such as WLEDs and plant cultivation.
