Abstract

In this study, Sm3+- and Dy3 -doped SrAl4O7 phosphors were synthesized by combustion method. X-ray diffraction (XRD) measurement confirmed the monoclinic crystal structure of SrAl4O7. Sr-O and Al-O bonds were identified by Fourier transform infrared (FTIR) spectroscopy. Under 352 nm excitation, the SrAl4O7: Dy3+ phosphor shown emission bands at 475 nm (blue) and 574 nm (yellow) that are due to 4F9/26H15/2,6H13/2 transitions, respectively. Photoluminescence spectra (PL) of SrAl4O7: Sm3+ phosphor has shown bright orange red emission at 598 nm with an excitation wavelength of 405 nm. The decay curve of Sm3+ and Dy3+ single doped SrAl4O7 phosphors were well fitted to a bi-exponential function. The obtained results show that the prepared phosphors may be applicable in the field of eco-friendly solid state lighting technology.
