Light/Force-Sensitive 0D Lead-Free Perovskites: From Highly Efficient Blue Afterglow to White Phosphorescence with Near-Unity Quantum Efficiency

Shangwei Feng et al.

Summary: New types of zero-dimensional perovskites with blue room-temperature phosphorescence were obtained and found to be highly sensitive to external light and force stimuli. The quantum yield of blue phosphorescence was enhanced and high-efficiency white phosphorescence was achieved by introducing Sb3+. This work overcomes the challenges of low quantum yield and short lifetime of blue phosphorescence, providing a feasible method for achieving high-efficiency white phosphorescence.

Tailored Fabrication of Carbon Dot Composites with Full-Color Ultralong Room-Temperature Phosphorescence for Multidimensional Encryption

Yuanfei Ding et al.

Summary: A facile method was developed to fabricate boron-doped carbon dot composites with full-color long lifetime RTP, which can be tailored by adjusting the mass ratios of citric acid and boric acid precursors and the pyrolysis temperature. The phosphorescence can shift from blue to red by increasing the citric acid feeding or higher pyrolysis temperature.

Room-Temperature Phosphorescence Enabled through Nacre-Mimetic Nanocomposite Design

Xuyang Yao et al.

Summary: A novel waterborne strategy is introduced to fabricate low-cost nanocomposite films with room-temperature phosphorescence (RTP), allowing programmable retention times of RTP signals by adjusting the polymer/nanoclay ratio for information storage and anti-counterfeiting materials. The combination of bioinspired nanocomposite design with RTP materials overcomes limitations in organic RTP compound molecular design and adds programmable temporal features to RTP materials, paving the way for practical applications as novel anti-counterfeiting materials.
