Figure 4From: Color-tunable properties of Eu3+- and Dy3+-codoped Y2O3 phosphor particlesPL emission spectra and integrated luminescence emission intensity (612-nm peak). PL emission spectra of Y2O3 phosphor particles codoped with different Eu3+ and Dy3+ contents (a) and integrated luminescence emission intensity of 612-nm peak as a function of RE ion concentration (b) upon constant 254 nm excitation.Back to article page
