The energy transfer process from Ce3+ to Tb3+ in Ca6Ba(PO4)4O and its mechanisms have been studied.
The higher power-sensitization triggers welding of the structure, favoring energy transfer between nanoparticles in Er3+/Yb3+ co-doped VO2.
When Eu3+ and Tb3+ ions are co-doped into the ZBH matrix, the phosphor yielded tunable emissions. The concentration of rare earth doped can change the composition and further change the morphology and the luminescence properties.
