摘要： A beta-voltaic device made up of silica covered scintillating particles incorporated within an isotope absorbing layer to produce an improved power source. Lost beta particles are converted to UV light which is also converted to power in a beta-voltaic converter. The addition of the scintillating particles effectively increases the power efficiency of a BV device while maintaining the slim profile and smaller size of the power source. This arrangement makes possible implementation in space, defense, intelligence, medical implants, marine biology and other applications.

摘要： The present disclosure relates to a core-shell type quantum dot, comprising a quantum dot core, a light-transmitting inorganic mesoporous material layer on a surface of the quantum dot core, and a filler different from the inorganic mesoporous material in mesopores of the light-transmitting inorganic mesoporous material layer. The present disclosure also relates to the preparation and use of the core-shell type quantum dot core. The quantum dot core is coated with the light-transmitting inorganic mesoporous material and the mesopores of the inorganic mesoporous material are filled with the filler different from the inorganic mesoporous material, and the core-shell type quantum dots thus obtained not only have improved optical stability and chemical stability, but also have adjustable optical properties.
