Nanosized phosphors based on Gd₁₋ₓEuₓPO₄ obtained by low-temperature methods
Nanowires (10 to 50 nm wide, up to 2 μm long) and nanoplates (60 to 100 nm wide, 70 to 500 nm long) of europium doped gadolinium orthophosphate with narrow size distribution have been obtained by precipitation from aqueous solution using microemulsion and ultrasound treatment. The crystal structure...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Nanowires (10 to 50 nm wide, up to 2 μm long) and nanoplates (60 to 100 nm wide, 70 to 500 nm long) of europium doped gadolinium orthophosphate with narrow size distribution have been obtained by precipitation from aqueous solution using microemulsion and ultrasound treatment. The crystal structure of all nanosized samples belong to monazite structure. The size and shape of the objects has been shown to influence the luminescence spectra of activator. It is concluded that, the concentration of europium ion localization sites in low symmetry position with respect to the central ions increases in nanosized matrices as compared to GdPO₄:Eu³⁺ polycrystals. |
