One-dimensional (Y, Gd) BO₃: Tb³⁺nanofibers with hexagonal structure have been prepared as potential green phosphors by an electrospinning technique, and characterized with X-ray diffraction,<b style=""> </b>scanning electron microscopy, FT-IR spectrum, TG-DTA and photoluminescence spectra. The effect of annealing temperature on the crystallization and luminescence properties has been studied. The main emission position is centered at 543 nm (⁵<i style="">D</i>₄ →⁷<i style="">F</i>₅). Photoluminescence spectra indicate that fluorescence capability improves with increase in temperature.
