“…Urea decomposition was reported by Akinc and coworkers [91,92] and Matijevic and coworkers [61,71,72] in the late 1980s and early 1990s. Since then, it has become one of the most favored CO 2 -source organic compounds in the laboratory synthesis of rare earth carbonates [59,68,74,75,[93][94][95][96][97][98], particularly the orthorhombic hydroxycarbonates. Urea hydrolysis is rather slow at even 90 • C, but is accelerated by the presence of lanthanide salts.…”

A general overview of the trends in structural and thermodynamic properties that have been identified within the hydrated normal rare earth carbonates and the rare earth hydroxycarbonates is presented. Based upon available literature, we demonstrate the trends in crystallographic unit cell parameters, thermal stability, aqueous solubility, and thermochemical properties. These trends can be attributed to both the unique chemistry and strong similarity of the rare earth elements. There are also inconsistent trends that signal research needs to better understand the structure-energy relationships of the rare earth carbonates.

The feasibility of utilizing the method of phosphor layer structure optimization to improve the performance of beta‐radioluminescent nuclear batteries is investigated. The designs of different V‐groove structures and conventional planar structures of ZnS:Cu phosphor layers are discussed. Monte Carlo simulations have been used to analysis the transportation of beta‐particles released from the 63Ni and 147Pm plate sources, along with the corresponding energy deposition in the phosphor layers. Radioluminescence properties are characterized and the influence of configuration parameters on the luminescence intensity and emission wavelength is revealed. The current–voltage characteristic curves of beta‐radioluminescent nuclear batteries with the above phosphor layer structures are used to analyze the electrical properties. Additionally, the deposited energy in the phosphors and radioluminescence luminous flux as a linear function of the maximum output power are investigated for different combinations of those phosphor layers and beta sources.

Summary Radioluminescent nuclear battery is a type of energy conversion device that can be miniaturized, which has the ability to convert nuclear energy into light energy, and again into electrical energy. To explore the response relationship between the phosphor layer structure and the electrical performance of radioluminescent nuclear battery, the physical model was established to research the deposition energy distribution by using Monte Carlo method. The radioluminescence spectra and current‐voltage characteristic curves were used to investigate the optical and electrical properties. Through a comprehensive comparison of single plane layer, double plane layer, and V groove layer structures, the simulated results are consistent with experimental results. The results indicate that the Monte Carlo simulation is applicable to analysis of the phosphor layer structure of radioluminescent nuclear battery. Additionally, the results also show that the structure type and physical parameters of the phosphor layer have great influence on the energy deposition. A suitable phosphor layer structure can provide a new route to exhibit higher energy conversion efficiency as well as improving the matching degree between the range of radioactive particles and the thickness of the phosphor layer.
