Achieving Luminescence of Sr₃Ga_1.98In_0.02Ge₄O₁₄:0.03Cr³⁺ via [In³⁺] Substitution [Ga³⁺] and Its Application to NIR pc-LED in Non-Destructive Testing

Molecules, 2023
Cr3+-doped Sr3Ga2Ge4O14:0.03Cr3+ (SGGO:0.03Cr3+) phosphor was synthesized via a high-temperature solid-phase method. Considering the tunable structure of SGGO, Ga3+ ions in the matrix were substituted with In3+ ions at a certain concentration.

Sr and Mg Doped Bi-Phasic Calcium Phosphate Macroporous Bone Graft Substitutes Fabricated by Robocasting: A Structural and Cytocompatibility Assessment

Journal of Functional Biomaterials, 2022
Bi-phasic calcium phosphates (BCPs) are considered prominent candidate materials for the fabrication of bone graft substitutes. Currently, supplemental cation-doping is suggested as a powerful path to boost biofunctionality, however, there is still a ...
