A new hybrid manganese bromide, (PP13)2MnBr4 (PP13+ = N-propyl-N-methylpiperidinium), was synthesized through a facile and environmentally friendly method. (PP13)2MnBr4 shows bright green photoluminescence with a high quantum yield of 63.98%. Its photoluminescence (PL) intensity significantly decreases during the phase transition, accompanied by a pronounced dielectric anomaly. Interestingly, (PP13)2MnBr4 demonstrates excellent scintillation performance under X-ray excitation, with a light yield of 24124.4 photons/MeV. The temperature-sensitive luminescence and dielectric properties of (PP13)2MnBr4, combined with its excellent X-ray detection capability, suggest that (PP13)2MnBr4 has potential multifunctional applications in the optoelectronic field.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...
Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
