I going to work in the synthesis of fluorescent nanoparticles, but I like to compare the size and composition that are already synthesized with the nanoparticles that I like to propose!
There are so many types of fluorocent nanoparticles with different size and composition. for example quantum dots (QDs), metal nanoparticles, lanthanides (mainly Eu,Sm,Tb,Gd) doped metal oxides/fluride bassed upconverted nanoparticles, presently, fluorescent carbon nanoparticles (FCNs) are attracting considerable attention because of its low toxicity and high chemical stebility.
except that Hybrid Architectures Involving Fluorescent Nanoprobes are also promissing, that includes Metal–Dye,Dye-doped Silica Shells,Quantum Dot-containing Microspheres.
