Ultrasound assisted sonochemical synthesis of ZrO2: Eu3+ nanophosphor

Eu³⁺ ions doped (1 - 7 mol %) ZrO₂ nanoparticles (NPs) were synthesized by a facile green synthesis method using Alove vera as fuel. The obtained ZrO₂: Eu³⁺ (1-7 mol %) NPs were characterized by using powder X-ray diffraction studies (PXRD), Raman studies and photoluminescence (PL) techniques. The dependency of dopant concentration on the crystal structure and luminescence properties were discussed in detail. The PL emission of ZrO₂: Eu³⁺ NPs shows characteristics transitions of Eu³⁺ ions. The CIE chromaticity and CCT confirms the phosphor material as red emitting hence it was quite useful in display applications.
