可调谐多色发光和能量转移
Tunable multicolor luminescence and energy transferThe phenomenon where the emission color of a phosphor can be adjusted by varying doping concentrations or external conditions, and the non-radiative transfer of energy between different dopant ions (e.g., Er3+ and Sm3+) within a host lattice. / 磷光体发射颜色可通过改变掺杂浓度或外部条件进行调节的现象，以及宿主晶格内不同掺杂离子（如Er3+和Sm3+）之间的非辐射能量转移。
