Hexamethyldisilazane-assisted Mn²⁺ doping of perovskite nanocrystals under ambient conditions

Abstract

Doping Mn2+ ions into lead halide perovskite (LHP) nanocrystals (NCs) has attracted great attention in the optoelectronic fields due to the stability enhancement and unique dual-color emission characteristics arising from...

Room-temperature synthesis of Ag- and Mn-doped Cs2NaBiCl6 octahedrons for dye photodegradation

“…The latter originates from the energy transfer from the host perovskites to dopant (i.e., Mn 2+ cations). [49][50][51][52][53] The Mn-doping was also utilized in LFDP materials to modulate the optical performances via the efficient energy transfer between the host and guest. 20,25,54,55 In our case, the orange-red emission upon Mn doping was blue-shifted from around 615 nm to around 580 nm and the PL intensity was heavily increased, in comparison with the very poor PL in the undoped samples.…”
