Influence of Sintering Temperature on Judd–Ofelt Parameters and Emission Properties of Y₁.₉₆Al₀.₀₄O₃:Eu³⁺ Phosphor for n-UV Excited Red Emission Applications.

Novelty of the Work

One of the major highlights of this research is the integration of a web-based Judd–Ofelt analysis platform (JOES) for automated extraction of optical parameters directly from Eu³⁺ emission spectra. This significantly simplifies and accelerates the traditionally complex and time-consuming JO analysis process for luminescent materials research.

The study also establishes a strong correlation between sintering-induced structural modifications and optical performance, providing a pathway for engineering highly efficient rare-earth phosphors for advanced photonic devices. 

Future Research Potential

🔹 Optimization of rare-earth doped phosphors for WLEDs
🔹 AI-assisted photoluminescence analysis and material discovery
🔹 Development of high quantum efficiency display phosphors
🔹 Optical gain media and laser materials
🔹 Computational automation of Judd–Ofelt analysis for luminescent systems

Selected highlights from the results include:

• Enhanced red emission intensity with higher sintering temperatures
• Improved quantum efficiency and reduced non-radiative losses
• Strong stimulated emission characteristics for photonic applications.
