Abstract

The ZnS:Ce phosphor together with a co‐activator Y^3+^ ion shows a bright saturated blue luminescence whose spectrum is a band with a peak wavelength of 450 nm. The chromaticity coordinates are x = 0.15 and y = 0.09, and thus this phosphor would be good for the blue primary color in displays and light sources. The blue luminescence is due to the 5d‐4f internal transition of the Ce^3+^ ion. (Β© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

A luminescent mechanism was constructed for the broad band emission spectra of the X 1 phase of the Y 2 SiO 5 :Ce phosphor powder. Four Gaussian peaks fit to the cathodoluminescent (CL) and photoluminescent (PL) spectra were attributed to the two different sites (A1 and A2) of the Ce 3 + ion in the
