Luminescence properties and Judd-Ofelt theory analysis of Tb3+-Sm3+ co-doped glass ceramics containing Sr5F(PO4)3
Tb3+-Sm3+ co-doped glass ceramics containing Sr5F(PO4)3 phase were synthesized using the melting-curing-crystallization method. The best heat treatment condition for glass ceramics was determined to be at 750 °C for 1.5 h through the use of differential scanning calorimetry (DSC), X-ray diffraction (XRD), and transmittance curve analysis. With the Judd-Ofelt theory, the Judd-Ofelt strength parameters Ωλ (λ=2,4,6) for precursor glasses and glass ceramics were calculated. Fluorescence spectroscopy was used to study the optical properties of Tb3+-Sm3+ co-doped containing Sr5F(PO4)3 glass ceramics. The results demonstrated a significant enhancement in the luminescence performance of Sr5F(PO4)3 crystalline glass ceramics compared to the precursor glass. Fluorescence lifetimes and Dexter's theory demonstrate energy transfer from Tb3+ to Sm3+. The luminescent color of glass ceramics can be altered by varying the concentration of Sm3+ doping. The Tb3+-Sm3+ co-doped Sr5F(PO4)3 phase glass ceramics exhibit promising potential for application in the field of W-LEDs.
期刊介绍：
The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid.
In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
