Abstract

Future electric lights will be composed of white LEDs (Light Emitting Diodes) and for this reason the development of new luminescence materials has become a great challenge to researchers. In the present paper it is presented a sol-gel method, simple and with superior potential for synthesis of nanoparticles of yttrimn aluminium garnet doped with cerium luminescent powders. This method has a big potential for application in new generation luminescent lighting devices. The gels were prepared using stoichiometric amounts of reagent-grade Y₂0₃ and A1₂0₃ as the starting materials. The XRD pattern of the powder calcinated al 1100°C shows the formation of single-phase nano-crystal garnet materials. The XRD measurements and AFM measurements show that we obtained a phosphorus with grain size of 24 nm. The emission spectra of white LED demonstrate that acquired phosphor has good applicability in optoelectronics.
