Abstract
Eu3+ doped K2La2Ti3O10 (KLT) phosphors were prepared by means of conventional solid state reaction method. It has exhibited an intense excitation band at around 466 nm, which matches well to the popular emission line from a GaN based blue light-emitting diode (LED) chip. Using this as an excitation wavelength the Eu3+ doped KLT phosphors yielded two strong orange-red emission bands at 595 nm (5D0→7F1) and 616 nm (5D0→7F2) respectively. The obtained results suggest that Eu3+doped KLT phosphors are useful for blue chip white LEDs. Besides we have studied its dielectric properties along with the other significant characterizations like XRD, SEM and Tg-DTA.
