Rare-earth doped crystalline materials are of significant interest for photonic and optoelectronic applications, particularly in phosphor-converted white-light-emitting diodes (pc-WLEDs), which offer high brightness, energy efficiency, compact size, durability, and environmental friendliness. However, pc-WLEDs lack a red color component. To address this, europium-doped niobate-based phosphors were synthesized using a high-temperature solid-state reaction technique at 1300°C[1].
