Fundamental understanding of the effect doping on optical properties 3D double perovskites (DPs) especially dynamics self-trapped excitons (STEs) is vital importance for their optoelectronic applications. Herein, a unique strategy via Cu+ to achieve efficient STE emission in alloyed lead-free Cs2 (Ag/Na)InCl6 DPs reported. A small amount (1.0 mol%) results boosted crystals, with photoluminescence (PL) quantum yield increasing from 19.0% 62.6% and excitation band shifting 310 365 nm....
Abstract Lanthanide doped upconversion nanocrystals, showing bright future in diverse fields, are typically excited by ≈700–1000 nm light when Nd 3+ and Yb used as sensitizers. Thus far, extending the excitation range of nanocrystals is still a formidable challenge. Herein, new type reported, using Er ions sensitizers, which can be 1532 located second near‐infrared biological window. Through sensitization, emission from series activators, including , Ho Eu Tm obtained modulated codoping. In...
Doping is an effective strategy for tailoring the optical properties of 0D Cs4PbX6 (X = Cl, Br, and I) perovskite nanocrystals (NCs) expanding their applications. Herein, a unique approach reported controlled synthesis pure-phase Mn2+-doped Cs4PbCl6 NCs excited-state dynamics Mn2+ unveiled through temperature-dependent steady-state transient photoluminescence (PL) spectroscopy. Because spatially confined structure perovskite, exhibit drastically different PL in comparison with 3D CsPbCl3...
The perfect energy level overlap of 2H11/2, 4S3/2, and 4F9/2 in Er3+ ions with those 5F3, 5F4/5S2, 5F5 adjacently codoped Ho3+ allows efficient interenergy transfer. Therefore, addition to routine activators, or can further act as sensitizers transfer the upconverted nearby Er3+, resulting enhanced upconversion luminescence due emission overlap. Proper codoping Er3+/Ho3+ Ho3+/Er3+ obviously elevates maximum doping concentration (thus producing additional photons) a higher than that causing...
