Synthesis and Characterisation of Y2O3: Eu/Ag powders (original) (raw)

Luminescent materials have a wide range of applications, such as organic light emitting devices, inorganic light emitting diode devices, displays, bio detections, etc. In this research, we showed the synthesis of Y 2 O 3 (core): Eu (dopant)/Ag (shell) powders through Ultrasonic Spray Pyrolysis in scale up conditions at 800 °C with a flow rate of air and at constant concentration of yttrium nitrate, europium nitrate and silver nitrate according the previously performed experiments. Detailed characterisation was performed on the produced Y 2 O 3 :Eu/Ag powder using STEM, SEM and EDX analysis. Microstructure observation showed that Y 2 O 3 :Eu/Ag powders are spherical, containing 50 % yttrium oxide, 45.2 silver and 0.65 europium.
