Intense Blue Emission Energy Transfer Analysis in Ce³⁺-Eu²⁺ Activated NaBa(PO₃)₃ Phosphors for Blue LEDs and Plant Growth Technologies

Phosphites are being recognized as the new emerging candidates for luminescence in the modern era. In the proposed research article, Ce³⁺/Eu²⁺ co-activated NaBa(PO₃)₃ phosphite phosphors synthesized utilizing sol-gel technique. Through the use of XRD and Rietveld refinement, the phase identity and crystal structure of produced phosphor are examined. SEM is employed to analyze the morphology and elemental composition of the prepared sample. The sample shows blue emission enhancement in the phosphor on energy transfer with the Ce³⁺ ion by 6 times. This highly instance blue emitting phosphor has color purity of 98.49%. These all results confirm that the prepared phosphor is potential candidate for WLEDs, display applications and blue emitting phosphor for plant cultivation applications.
