In this work, the local rice husk ash collected from rice paddy in Suphan Buri province was used to study the utilization as a SiO₂ chemical substitute to fabricate the glass samples doped with praseodymium. The ash was calcined at various calcination temperatures and studied its chemical components. The glasses with formular SiO₂(RHA)-B₂O₃-Na₂O-CaO-Pr₂O₃ were prepared by melt - quenching technique and were studied through various scientific instruments to obtain their properties. The measurements revealed that as the Pr₂O₃ concentration increased, the density along with the molar volume increased. The intensity of all absorption bands increases with Pr₂O₃ concentration when measuring the absorption spectra of glasses in the 200 - 2,500 nm range. Additionally, using a 444 nm excitation wavelength, the photoluminescence characteristics of Pr³⁺ doped-SiO₂(RHA)-B₂O₃-Na₂O-CaO-Pr₂O₃ glasses were seen and found the emitted light around the 605 nm band.
