Dosimetric investigations of Tb³⁺ doped strontium silicate phosphor

In past few decades, silicates are found to exhibit excellent luminescent properties in the blue, green and red spectral regions. Eu²⁺ doped Strontium Silicate is known to be an excellent yellow phosphor applicable in LED based solid-state lighting applications. Tb³⁺ doped Mg₂SiO₄ is known to be a promising TLD material for the dosimetry due to high TL sensitivity and its use to access the real time dose has been recently reported. Also amongst several rare earths, Tb³⁺ is known to be used as a green light emitting luminescent materials because of the ⁵D₄-⁷F₅ transition peak at around 545 nm of the Tb³⁺ ion. However, luminescence properties of SrSiO₃:Tb³⁺ has been rarely studied. In this paper we report the dosimetric properties of Tb doped SrSiO₃ synthesized by co-precipitation technique
