Electrophoretic deposition of Eu2+ doped Ca-α-SiAlON phosphor particles for packaging of flat pseudo-white light emitting devices

Electrophoretic deposition of Eu2+ doped Ca-α-SiAlON phosphor particles for packaging of flat pseudo-white light emitting devices

The preparation of Eu2+ doped Ca-α-SiAlON phosphor films were conducted on ITO glasses by electrophoretic deposition (EPD). The thickness of the SiAlON phosphor films was controlled by altering the deposition time. The photoluminescent (PL) properties of the SiAlON phosphor films were characterized...

description The preparation of Eu2+ doped Ca-α-SiAlON phosphor films were conducted on ITO glasses by electrophoretic deposition (EPD). The thickness of the SiAlON phosphor films was controlled by altering the deposition time. The photoluminescent (PL) properties of the SiAlON phosphor films were characterized by blue-light (λ = 450 nm) irradiation through the ITO glass substrates. The light emission from the deposit surfaces was characterized by comparing the intensities of the excited yellow light and the transmitted blue light. The chromaticity coordinates were calculated from the PL spectra and compared with actual colors perceived by human eyes.
