Yttrium hydroxide can have applications as optical material being used to obtain luminescent phosphors that have emission in visible spectral region [1]. Y(OH)3 can serve as host lattices being activated by rare-earth cations as europium. Eu3+ emits red color while the yttrium collects energy and passes it to the phosphor. Besides Eu3+ also Tb3+ can be used as a doping agent leading to green luminescence in this compound [2]. We obtained Y(OH)3 powder hydrothermally, in unreported short time 3-4 h. XRD pattern show that product is in hexagonal crystal system with the space group P63/m. The material is stable in time. SEM micrograph show a tube like morphology and micronic dimensions of material. Relatively large band gap of this material make it interesting from point of view of dopability. In this work we intend to analyze by the optical methods UV –Vis absorption, photoconductivity (PC) and photoluminescence (PL), the band-gap, purity and light emissive properties of pure Y(OH)3 and doped compound. UV-Vis spectroscopy shows absorption in UV and broad absorption in visible region and at room temperature. PL spectra of of pure Y(OH)3 excited with 3.49eV (355nm) at room temperatures, shows several peaks of emission in visible region at 3.04 eV (410 nm), 2.78eV (445 nm) and 2.20 eV (610 nm). First can be attributed to the band to band emission and other to the inside band gap transitions. Further characterization is underway. The further work will be focus to increase light emissive properties in visible region by doping Y(OH)3 Acknowledgements This work is supported by Marie Curie Initial Training Network (ITN) - SOPRANO , Grant No. PITN-GA-2008-214040.
