White-light-emitting diodes (WLEDs) were fabricated by combining a yellow ${\mathrm{Sr}}_3{\mathrm{SiO}}_5:{\mathrm{Ce}}^{3+},{\mathrm{Li}}^{+}$ phosphor with a blue light-emitting diode (LED) ( $460\mathrm{nm}$ chip) or a near ultraviolet (n-UV) LED ( $405\mathrm{nm}$ chip), respectively. Color temperature $\left(T_c\right)$ of ${\mathrm{Sr}}_3{\mathrm{SiO}}_5:{\mathrm{Ce}}^{3+},{\mathrm{Li}}^{+}$ -based WLEDs could be tuned from 6500 to $\mathrm{100,000}\mathrm{K}$ (blue LED pumping) and from 4900 to $\mathrm{50,000}\mathrm{K}$ (n-UV LED pumping) without mixing with other phosphors. The blue LED-pumped WLED showed excellent white light (luminous efficiency= $31.7\mathrm{lm}∕\mathrm{W}$ , $T_c=6857\mathrm{K}$ ) at $20\mathrm{mA}$ . This WLED showed a stable color coordinates property against an increase of the forward current. An n-UV LED-pumped WLED also showed bright white light ( $25.0\mathrm{lm}∕\mathrm{W}$ , $5784\mathrm{K}$ ) at $20\mathrm{mA}$ .
