Realizing efficient broadband near-infrared emission and multimode photoluminescence switching via coordination structure modulation in Sb3+-doped 0D organic metal chlorides

“…S26 (ESI †) exhibits the absorption spectra of the samples. Compared with compound 1, the absorption spectrum of Sb 3+ -doped 1 shows four consecutive absorption bands, the bands at 269, 278, and 462 nm can be assigned to the 6 A 1 -4 A 2 (F), 6 A 1 -4 T 1 (F), 6 A 1 -4 T 1 (G) transitions of Mn 2+ , and the band at 375 nm is the 1 S 0 -3 P 1 transition of Sb 3+ (Fig. S26a, ESI †).…”

“…[1][2][3][4] What's more, broadband NIR light sources are highly needed because the diverse variety of organic components in food and human tissues have broad signature absorption signals in the NIR spectra (700-1000 nm). 5,6 Unfortunately, traditional broadband NIR light sources such as super-continuum lasers and halogen lamps have problems such as low efficiency, slow response, short lifetime, poor thermal stability, and so forth. 7,8 Therefore, this provides tremendous impetus for exploring a new generation of broadband NIR light sources with excellent performance.…”

Highly emissive Sb3+-doped Rb2InCl5·H2O perovskites: cost-effective synthesis, luminescence, and its application

“…[39][40][41] 0D In-based perovskites consisting of A 2 InX 5 ÁH 2 O (A = Cs, Rb; X = Cl, Br) have recently been explored. [42][43][44] Previous studies suggested that Sb 3+ -doped Cs 2 InX 5 ÁH 2 O (X = Cl, Br) possess admirable luminescence properties, making them promising materials for optoelectronic applications. 42,[45][46][47][48][49] Compared with the Cs 2 InX 5 ÁH 2 O (X = Cl, Br) perovskites, few reports are about their Rb-based counterpart (Rb 2 InX 5 ÁH 2 O; X = Cl, Br).…”
