Characterization Optical of ZnAl2O4 Doped with Eu3+ Functionalized with Chitosan


Article Preview

ZnAl1.,9Eu0.1O4 nanoparticles were functionalization used of the 3-aminopropyltrimethoxysilane silane and chitosan, in 5:1 proportion of the nanoparticles to chitosan, in order to obtain hybrid materials for the development of luminescent markers. The samples were characterized by XRD, FTIR, TEM, excitation and emission. After functionalized the nanoparticles showed formation of crystalline phase of spinel and chitosan. TEM results have revealed that the samples presented before particle size less than 100 nm and after functionalization was observed that the particle size increases. Emission peak of Eu centered at 614 nm, corresponding to the transition 5D0 7F2. Nanoparticles before and after functionalization showed the spectral lines characteristics of Eu ion 5D0 7Fj where (J = 0,1,2,3,4). After functionalization the sample presented an increase of luminescence intensity.
