| Summary: | In this paper, a series of [Sm2O3]x[(ZnO)0.5 (B2O3)0.1 (SLS)0.4]1-x, where × = 0, 0.01, 0.02, and 0.03 in weight
fraction was fabricated via melt-quenching method. The influence of the samarium ion (Sm3+) concentration on
the structural and optical properties was investigated. X-ray diffraction (XRD) and Fourier-transform infrared
spectroscopy (FTIR) confirmed the samples’ glassy (amorphous) behavior. The optical absorption intensity
enhanced as the dopant increased, whereas the optical band gap reduced with the progression of Sm3+ concentration. The sample’s refractive index and Urbach energy range from 2.145 to 2.203 and 0.682 eV to 0.713
eV, respectively. From the photoluminescence studies, 3 wt% Sm3+-doped samples indicate the most intense
emission in the orange-reddish region among the other samples. The calculated CIE coordinates for Sm3+ doped
ZnO–B2O3–SLS glasses are approximate (0.57, 0.43), near the Amber LED NSPAR 70BS produced by Nichia
Corporation. In addition, the CCT of the Sm3+-doped samples at about ~ 1750 K reveals prepared glass samples
have bright orange-reddish emission. These findings indicate that Sm3+-doped in ZnO-B2O3-SLS has enhanced its
orange-reddish emission and potential as an orange-reddish glass phosphor material in optoelectronic devices
such as glass phosphor for LEDs. |
