Figure 3From: Evaluating the use of blue phosphors in white LEDs: the case of Sr0.25Ba0.75Si2O2N2:Eu2+Photoluminescence spectra. Photoluminescence emission (excitation at 370 nm, solid lines) and excitation (emission at 466 nm, dashed lines) spectra of Sr0.25Ba0.75Si2O2N2:Eu2+, measured at room temperature (blue, thick lines) and at 10 K (black, thin lines).Back to article page
