Effect of Li and NH4 doping on the crystal perfection, second harmonic generation efficiency and laser damage threshold of potassium pentaborate crystals

The development of rare-earth combined Fe-based magnetic nanocomposites for use in biological theranostics

“…Doping strategy refers to the incorporation of impurity atoms or ions into the matrix materials, which can impart host materials with varying physical (morphology, 90 size, 91 and crystallographic phase 92 ) and chemical (optics, 93 magnetism, 94 and catalysis 95 ) properties. The differences in ionic size, valence state, and reactivity between the dopants and host elements prominently determine the capability of its occurrence.…”
