Color-tunable room temperature phosphorescence (RTP) materials possess potential applications in multicolor imaging, multichannel anticounterfeiting, and information encryption. Herein, we synthesized two zero-dimensional cadmium-organic halides, (H-aepy)CdX (referred to as ; X = Cl, Br; aepy = 3-(2-aminoethyl)pyridine), both of which exhibit long-lived excitation wavelength- and time-dependent RTP. Experimental and theoretical results suggest that the multicolor RTP can be ascribed to the coemission of pristine H-aepy ligands and halogen-affected H-aepys, supporting that suitably introducing halogens can be an efficient strategy for constructing multicolor RTP materials. Additionally, we also demonstrate that the two phosphors can be applied in multichannel anticounterfeiting and information encryption. This work reports two hybrids with color-tunable RTP, as well as provides new insight into the effect of halogens on the regulation of RTP.
颜色可调的室温磷光（RTP）材料在多色成像、多通道防伪和信息加密方面具有潜在应用。在此，我们合成了两种零维镉有机卤化物，(H-aepy)CdX（简称为 ；X = Cl，Br；aepy = 3-(2-氨基乙基)吡啶），它们都表现出长寿命的激发波长和时间依赖性RTP。实验和理论结果表明，多色RTP可归因于原始H-aepy配体和卤素影响的H-aepys的共发射，这支持了适当引入卤素可以是构建多色RTP材料的有效策略。此外，我们还证明了这两种磷光体可应用于多通道防伪和信息加密。这项工作报告了两种具有颜色可调RTP的杂化物，并为卤素对RTP调控的影响提供了新的见解。
