Abstract

This paper reports the Stokes photoluminescence (PL) spectra of erbium-doped potassium niobate (KNbO₃), which are prepared by synthesized method. In this work, we research the relations between PL spectra with the sintering temperature and erbium concentration. The experiments showed that ²H_1/2→⁴I_15/2, ⁴S_3/2→⁴I_15/2 and the ⁴S_3/2→⁴I_13/2 emission peaks have maximum intensity at sintering temperature of 1060°C for the concentration of erbium (C_Er) = 1% sample. The PL spectra is also a function of dopant concentration. It was found that the relative intensity of ²H_1/2→⁴I_15/2, ⁴S_3/2→⁴I_15/2 and the ⁴S_3/2→⁴I_13/2 transitions increased as the concentration of erbium dopants increased, but then it decreased. The material characteristics were studied using X-ray diffraction, scanning electron microscopy and Raman spectrometer.
