Liquid-Phase Synthesis of Colloids and Redispersible Powders of Strongly Luminescing LaPO 4 :Ce,Tb Nanocrystals

Nanoparticles with high photoluminescence quantum yield have been recently considered as possible biolabels and as emitters in optoelectronic devices. Now gram amounts of nontoxic, chemically stable LaPO :Ce,Tb nanocrystals have been obtained in a coordinating solvent. These nanoparticles can be eas...

Description
Summary:Nanoparticles with high photoluminescence quantum yield have been recently considered as possible biolabels and as emitters in optoelectronic devices. Now gram amounts of nontoxic, chemically stable LaPO :Ce,Tb nanocrystals have been obtained in a coordinating solvent. These nanoparticles can be easily redispersed in polar solvents to give scatter-free colloids that exhibit quantum yields of up to 61 %.
