Ratiometric luminescent temperature sensor based on amorphous complex of europium (III) and quantum dots
This work reports synthesis of core-shell CdSe/CdS/ZnS quantum dots (QD) and the amorphous β-diketonate Eu(CPDK3–5)3bpy17–17 complex. Oleic and stearic acids were used to stabilize colloid nanoparticles and disperse them in organic solvents. Hybrid films of polymethyl methacrylate with various mass...

| description | This work reports synthesis of core-shell CdSe/CdS/ZnS quantum dots (QD) and the amorphous β-diketonate Eu(CPDK3–5)3bpy17–17 complex. Oleic and stearic acids were used to stabilize colloid nanoparticles and disperse them in organic solvents. Hybrid films of polymethyl methacrylate with various mass ratios of doped quantum dots and europium complexes were produced by spin-coating. The application potential of these materials as ratiometric temperature sensors was analyzed. The produced films demonstrated the highest sensitivity of photoluminescence in the temperature range of 298 – 393 K among other known analogues. |
