Synthesis and multicolor luminescence of Tb3+ and Sm3+ co-doped LiGd(MoO4)2 phosphor

Color tunable Gd2O3: Tb3+/Eu3+ nano-phosphors prepared via laser ablation in water

“…The decay curves of sample Gd 2 O 3 :5%Tb, yEu (y= 0.1%, 1%, 3% and 5%) nano-phosphors conform to double exponential fitting [36]:…”

“…The results of fluorescence lifetime show the existence of energy transfer process from Tb 3+ to Eu 3+ ions. The energy transfer efficiency can be roughly calculated from the intensity of the emitted light: [36]…”

A novel optical temperature sensor and energy transfer properties based on Tb3+/Sm3+ codoped SrY2(MoO4)4 phosphors

“…7c. 44 The curves show the variation trend of the maximum emission intensity with Sm 3+ ion concentration (green represents Tb 3+ ions and red represents Sm 3+ ions). The characteristic emission of Tb 3+ ions is apparent by the emission peaks at 490 nm and 548 nm.…”
