Abstract

The development of multifunctional phosphors with optical temperature sensing and advanced anti-counterfeiting is of great significance but remains considerable challenges. Herein, a series of Bi³⁺/Mn⁴⁺ co-doped La₂CaSnO₆ phosphors with double perovskite structure were successfully synthesized, and their luminescence properties and temperature sensing properties were investigated in detail. The tunable luminescence of the phosphors were achieved by adjusting doping concentration, excitation wavelength and ambient temperature. Based on the multi-mode tunable luminescence of La₂CaSnO₆: Bi³⁺, Mn⁴⁺ phosphors, the potential applications in the anti-counterfeiting field have been demonstrated by constructing complex patterns. Moreover, benefiting from the distinct thermal behaviors of Bi³⁺ and Mn⁴⁺ ions, the La₂CaSnO₆: Bi³⁺, Mn⁴⁺ showed good optical temperature sensing performance, achieving a maximum relative sensitivity (S_r) of 3.34% K⁻¹ at 323 K. These results indicate that La₂CaSnO₆: Bi³⁺, Mn⁴⁺ phosphors are promising multifunctional materials for applications in optical temperature sensing and anti-counterfeiting.

Bi3+/Mn4+共掺杂双钙钛矿荧光粉的可调谐发射

开发具有光学感温和先进防伪功能的多功能荧光粉具有重要的意义，但仍面临相当大的挑战。本文成功合成了一系列具有双钙钛矿结构的Bi3+/Mn4+共掺杂La2CaSnO6荧光粉，并对其发光性能和感温性能进行了详细的研究。通过调节掺杂浓度、激发波长和环境温度，实现了荧光粉的可调发光。基于La2CaSnO6: Bi3+， Mn4+荧光粉的多模可调谐发光特性，通过构建复杂的图案来展示其在防伪领域的潜在应用。此外，得益于Bi3+和Mn4+离子不同的热行为，La2CaSnO6: Bi3+， Mn4+表现出良好的光学感温性能，在323 K时的最大相对灵敏度（Sr）为3.34% K−1。这些结果表明，La2CaSnO6: Bi3+， Mn4+荧光粉是一种很有前途的多功能材料，可用于光学温度传感和防伪。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
