Doping-induced phase formations and luminescence of Eu3+-activated LaTiSbO6

Deciphering crystal structure of Li3Bi3Te2O12:Sm3+ phosphors with high thermal stability for plant cultivation and white light‐emitting diodes

“…At the same time, Li + is only found in the tetrahedral sites prevalent in garnet structures. The radius percentage discrepancy ( D r ) was used to confirm the substitution of dopant (Sm 3+ ) in the Li 3 Bi 3 Te 2 O 12 host, which can be calculated by Equation () as follow 36 : $$$$\begin{equation}{D}_r = \frac{{\left[ {{r}_1\left( {CN} \right) - {r}_2\left( {CN} \right)} \right]}}{{{r}_1\left( {CN} \right)}}\ ,\end{equation}$$$$where r 1 (CN) denotes the radius of Bi 3+ , which represents the host ions. On the other hand, r 2 (CN) corresponds to the radius of Sm 3+ , indicating the doped ions.…”
