Polymer-salt synthesis of Gd2O3:Nd3+ nanophosphors

Combustion synthesis and up-conversion luminescence of La2O2S:Er3+,Yb3+ nanophosphors

La2O2S:Er ,Yb nanocrystalline up-converting phosphors were synthesized by a combustion method at low temperature, using ethanol as pre-ignition fuel and thioacetamide as sulfurizing agent and organic fuel. The phosphors were characterized by powder X-ray diffractometry, scanning electron microscopy, UV/Vis/NIR spectroscopy and fluorescence spectroscopy. Pure and well-crystallized La2O2S:Er ,Yb ...

Europium-doped yttrium silicate nanophosphors prepared by flame synthesis

Europium-doped yttrium silicate (Y2SiO5:Eu ) nanophosphors were successfully synthesized by flame spray pyrolysis method. The effect of silicon concentration on the crystal structure and morphology of the Y2SiO5:Eu 3+ phosphors were investigated. Asprepared phosphor consists of spherical nanoparticles with filled morphology, high crystallinity, narrow size distribution, and intense photolumines...

A Review on Synthesis of Nanophosphors – Future Luminescent Materials

Nanophosphors have been extensively investigated during the last decade due to their application potential for various high-performance and novel displays and devices. Synthesis of nanophosphors is generally done by chemical methods. Under chemical methods, different routes such as colloidal, capping, cluster formation, sol-gel, electrochemical etc., are being followed. Physical methods widely ...
