Blue-red dual color emitting phosphor Cs2NaLuCl6: Sb3+, Ho3+ for plant growth LEDs

Realizing efficient photoluminescence spectral modulation via Sb3+/Ln3+ co-doping in Cs2NaInCl6 double perovskites

“…When Ho 3+ ions were doped into Cs 2 NaIn 0.95 Sb 0.05 Cl 6 , sharp narrow band emission peaks centered at 490 nm, 542 nm, and 657 nm were observed, which belong to the 5 F 3 , 5 F 4 , and 5 F 5 → 5 I 8 transitions of Ho 3+ ions. 41 respectively, as shown in Fig. 2(b).…”

Tunable dual-emission of Sb3+, Ho3+ Co-doped Cs2NaScCl6 single crystals for light-emitting diodes

“…The highest PLQY for Ho 3+ doping is 68%, and the total PLQY of the visible emission light maintain over 65% with different Ho 3+ concentrations (figure 4(b)). Compared to the literature reported to date, 68% of PLQY obtained exceeds most red-luminescent double perovskites (table S1) [23,24,[35][36][37][38][39][40][41][42]. Figure 4(g) illustrates the color transformation of Cs 2 NaScCl 6 :1%Sb 3+ and y%Ho 3+ SCs, from blue to magenta, and finally to red with an increasing concentration of Ho 3+ ions under UV lamp irradiation.…”

Novel dual spectral conversion via Eu2+, Cu+-coactivated core–shell-structured CaS@CaZnOS phosphors for efficient photosynthesis of plants

“…Therefore, the dual-excitation dual-emission (DE 2 ) phosphor, which can convert green/ultraviolet light into red/blue light simultaneously, is the ideal light-conversion auxiliary (LCA) for agricultural films. 15–17…”
