Modified luminescent properties from green afterglow to efficient orange emission in zirconium-based organometallic chloride scintillator by Sb3+ doping

Near-unity photoluminescence quantum yield in zero-dimensional lead-free indium-based hybrid perovskites by antimony doping

“…Rational ion doping is regarded as an effective strategy for improving photophysical properties. 18–20 For example, antimony( iii ) with the ns 2 electronic configuration is an effective dopant used as a non-emitting system to activate PL emission due to the unique dynamic lone pair of electrons. 21–23 Although relatively strong PL emission has been obtained, the PL quantum yield (PLQY) of the reported hybrid indium halide systems is still unsatisfactory.…”

Optical Property Regulation through Host–Guest Interaction in a Zero-Dimensional Zr Chloride

“…Besides inorganic Cs 2 ZrCl 6 , the organic cation hybrid Zr chloride can greatly enrich the crystal structures of A 2 ZrX 6 , thereby altering the material’s optical properties. For example, (TEA) 2 ZrCl 6 (TEA = tetraethylammonium), (TMA) 2 ZrCl 6 (TMA = tetramethylammonium), [(Ph 4 P) 2 ZrCl 6 ] 4 ·CH 3 CN (Ph 4 P = tetraphenylphosphonium), and (Ph 3 S) 2 ZrCl 6 (Ph 3 S = C 18 H 15 S) have various optical properties arising from the organic cation regulation. Compared with the protonated organic cation, the nonprotonated organic cations are not susceptible to deprotonation, thus enhancing the structural stability.…”

Dual Emission in Organic–Inorganic (C4H12N)2HfCl6 Perovskites via the Invocation of Bi3+/Te4+ Octahedron Clusters

“…Integrating auxiliary emission channels by metal-ion doping is an effective strategy to improve CRI and adjust CCT. In this regard, s -, d -, and f -electron ions, such as Bi 3+ , Sb 3+ , Te 4+ , Mn 2+ , Cr 3+ , Er 3+ , and Ho 3+ , have been established as effective dopants to generate auxiliary emissions. − Specifically, the doping ions with ns 2 electronic configurations can exhibit a series of blue, green, yellow, and red luminescence colors in 0D metal halide crystals. − However, most halide perovskites with a single dopant find it difficult to achieve multimode excitation and tunable or full-spectrum emission, limiting their further development. Compared with single doping technology, double doping is a simple and effective strategy to manipulate the photoluminescence (PL) performance of halide perovskites by breaking the parity-forbidden transitions and providing additional emission centers. − Double doping in a single composition emitter can exhibit lots of advantages in terms of device miniaturization, self-absorption, and color stabilization .…”
