  • Publication number: 20250075125
    Abstract: The invention provides luminescent lanthanide nanoparticles having simultaneously an improved brightness and an increased lifetime of the excited-state. These nanoparticles comprise terbium ions and ions of a second lanthanide, preferentially europium, and are coated with molecules of chromophore ligand bonded to the surface of the nanoparticle. The ligand is an organic molecule comprising at least one chromophore radical of formula I or of formula II: wherein R is selected from H, CN group or COOH group. The phosphorescence excited-state lifetime is improved by energy transfer from surface terbium ions to core ions of the second lanthanide.

  • Patent number: 11839998
    Abstract: Three-dimensional (3D) hierarchical morphologies widely exist in natural and biomimetic materials, which impart preferential functions including liquid and mass transport, energy conversion, and signal transmission for various applications. While notable progress has been made in the design and manufacturing of various hierarchical materials, the state-of-the-art approaches suffer from limited materials selection, high costs, as well as low processing throughput. Herein, by harnessing the configurable elastic crack engineering-controlled formation and configuration of cracks in elastic materials, an effect normally avoided in various industrial processes, the present invention provides a facile and powerful technique to enable the faithful transfer of arbitrary hierarchical structures with broad material compatibility and structural and functional integrity.

  • Patent number: 11837842
    Abstract: The present invention relates to a solid-state blended polymer system that has the property of tunable lasing wavelength through adjusting the blending ratio. It can be used for health monitoring, environmental monitoring sensor and tissue imaging. Current materials do not have the broad tunable range; from blue to infra-red across the optical range. By using the same two polymers, it is possible to produce laser emitting blue to red colour. It simplifies the design, eases multi-wavelength laser sensor system integration and therefore, making the production cost-effective.

  • Patent number: 11444256
    Abstract: This invention provides a filter-free tunable spectrum PD with a layered structure of at least two electrodes and two functional layers. Both functional layers can be a layer, a stack of inorganic semiconductors, an organic semiconductor, an organic/polymer donor/acceptor blend, a hybrid semiconductor or their combinations that has a good charge transport property. The first functional layer absorbs the shorter-wavelength EM waves and is transparent to the longer-wavelength EM waves. The second functional layer absorbs the longer-wavelength EM waves. The detection spectrum window is determined by the difference in wavelengths between the transmission cut-off wavelength of the first functional layer and absorbing edge of the second functional layer, or between the absorption edge of the first functional layer and that of the second functional layer.

  • Patent number: 11329239
    Abstract: The present invention relates to a bias-switchable spectral response high performance PD with multi-mode detection, e.g., dual-mode photoresponses in NIR and visible light ranges. The dual-mode PD has the absorber/spacer type components in its active layer, e.g., a tri-layer configuration of absorber-1 (absorber-1 absorbs the electromagnetic wave of the first wavelength comprising visible light)/optical spacer/absorber-2 (absorber-2 absorbs the electromagnetic wave of the second wavelength comprising IR light). In the presence of IR light, photocurrent generates in the IR light absorbing layer under a reverse bias. In the presence of visible light, photocurrent generates in the visible light absorbing layer under a forward bias. A bias-switchable spectral response PD offers an attractive option for applications in environmental pollution, bio, medical, agricultural, automotive, fishery, food, wellness and security monitoring, detection and imaging in two or different or multiple distinct bands.
