- 論文の詳細を見る
The laminated or mixed films of SiAlON phosphors were prepared on ITO glasses by electrophoretic deposition (EPD). Three types of SiAlON phosphors, Eu doped Ca-α-SiAlON, β-SiAlON and CaAlSiN3, which emit the lights of yellow (λ = 585 nm), green (540 nm) and red (620 nm), respectively, were used for the color tuning. The photoluminescence (PL) properties of the laminated or mixed films were characterized by blue-light (λ = 450 nm) irradiation through the ITO glass substrates. The effects of the lamination or mixture of the phosphors are characterized by the broadness of the PL spectra.
