Spectroscopic properties of new phosphor Y2O3:Ti 3+ for white LEDs

Abstract

Abstract:

Y₂O₃:Ti ³⁺powders were prepared by coprecipitation method at different temperatures in different sintering atmospheres. XRD spectra, excitation and emission spectra of Y₂O₃:Ti ³⁺powders were measured, and their morphologies were observed. Under the excitation of UV light, Y₂O₃:Ti ³⁺ microcrystalline has a strong emission band near 439nm, and Y₂O₃:Ti ³⁺ nanocrystalline has a more stronger emission band in the range of 400-500nm. The fluorescence of Y₂O₃:Ti ³⁺ nanopowder becomes strong observably as the grain size reduces, and the fluorescence covers whole visible light region. This indicates that Y₂O₃:Ti ³⁺ nanopowder is expected to become a new generation light conversion phosphor for white LED or mercury lamp.

Key words: materials, nanopowder, white LED, phosphor, Y₂O³Ti ³⁺
