Summary: The photoluminescence properties of Dy3+ doped Na0.5Bi0.5TiO3 lead-free ferroelectric ceramics were systematically studied, showing strong emission under a specific excitation wavelength suitable for warm white light. The ceramic exhibits optimal luminous performance at a Dy3+ content of 0.012, but experiences significant thermal quenching of luminous intensity at temperatures above 293 K.

Summary: By controlling the long-range ferroelectric ordering (LRFO) in lead-free piezoceramics, multifunctional properties such as increased piezoelectric coefficient and temperature-insensitive strain can be achieved. Low antimony doping maintains LRFO and results in multi-phase coexistence near room temperature, while high antimony doping leads to a relaxor phase transition.

Summary: A novel fluorescent probe combining nitrogen-doped carbon dots and quantum dot platform has been developed for highly sensitive H2O2/glucose detection and pH sensing. The dual-color ratiometric fluorescent probe effectively detected H2O2 by utilizing blue fluorescence NCDs and yellow fluorescence CdTe QDs, while the pH sensing system was based on the loss of passivation and doping effects in CdTe QDs and N-CDs. The bimaterial system showed promising results in semi-quantitative pH detection and glucose assay in spiked serum samples.

Summary: This article introduces a simple mechanism using a monolithic, bandgap-engineered photoferroelectric ceramic to blindly measure the wavelength and intensity of incident light. The photoferroelectric compound, Ba- and Ni-doped (K, Na)NbO3, exhibits a direct bandgap of approximately 2 eV and a spontaneous polarization of approximately 0.25 C m(-2), allowing reliable distinction of wavelengths and power density. The proposed alternative offers filterless, wavelength-selective photodetection and color sensing.
