Effective light management, stretchable and transparent nanofiber electrode via the incorporation of phosphors into composite nanofibers for wearable perovskite solar cells

“…7 F J (J ¼ 0, 1, 3) transitions. 36 When the emission at 545 nm was monitored, a strong peak at 304 nm in the PLE spectrum was found, due to the charge inner transitions of 4f 8 ! 4f 7 5d allowed by the electric dipolar parity.…”

“…30 When the Y 2 O 3 :Eu 3+ NPs were excited by the light at 254 nm, a strong emission peak at 613 nm due to charge transitions of 5 D 0 → 7 F 2 , and a few weak emission peaks in the range of 500–650 nm, were assigned to 5 D 1 → 7 F 1 and 5 D 0 → 7 F J (J = 0, 1, 3) transitions. 36 Figure 5(b) demonstrates the PL spectrum and photoluminescence excitation (PLE) spectrum of Y 2 O 3 :Tb 3+ . When the emission at 545 nm was monitored, a strong peak at 304 nm in the PLE spectrum was found, due to the charge inner transitions of 4f 8 → 4f 7 5d allowed by the electric dipolar parity.…”

Study of the thermal stability and decomposition behaviour of Lu(NH 4 )(C 2 O 4 ) 2 ·2H 2 O

“…Rare earth elements, because of their unique electronic layer structure, have excellent physical and chemical property properties, such as light, electricity and magnetism [1]. It is widely used in luminescent materials [2][3][4][5][6][7], magnetic materials [8,9], hydrogen storage materials [10], high performance ceramic materials [11][12][13], amorphous alloys [14], catalytic materials [15][16][17][18][19][20] and solid fuel cell electrolytes [21][22][23], which are indispensable core foundation material and have gained particular attention [24]. With the development of the application levels, the quality requirements for rare earth oxides have changed from simple chemical composition and purity to controllable crystal structure, particle size, morphology and specific surface area.…”
