(Hmpy)MnCl₃ (Hmpy = N-methylpyrrolidinium) with a one-dimensional AMnX₃ perovskite shows an obvious dielectric anomaly, a broad dielectric dispersion of the temperature range from 296 to 400 K, and brilliant red fluorescence at 632 nm with a high quantum yield of 54.54% under UV excitation.

Discover & Discuss Important Research

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.

Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform.
