Metal‐organic frameworks (MOFs) are known for their versatility in terms of their crystalline structure, porosity, resistance to temperature, radiation damage, and luminescence among others. Gadolinium (Gd) is one of the elements with the highest reported cross‐section for low energy neutron capture, producing internal conversion electrons and γ rays as a result of the neutron absorption. The development of Gd‐BTC films (BTC=1,3,5‐benzenetricarboxylate) is shown that were deposited on Si and Al substrates by airbrushing, and characterized by profilometry, Raman, EDX and X‐ray diffraction. Radiation damage, thermal decomposition and neutron absorption of these films were studied as well. Gd‐BTC films were attached to CMOS devices (Complementary Metal‐Oxide‐Semiconductor), which are sensible to the internal conversion electrons, in order to build a neutron detector. The devices Gd‐BTC/CMOS could selectively detect neutrons in the presence of γ rays with a thermal neutron detection efficiency of 3.3±0.1 %, a signal to noise ratio of 6 : 1, and were suitable to obtain images.

Metal金属有机骨架膜作为中子检测的转换层

金属有机骨架（MOF）以其晶体结构，孔隙率，耐温性，辐射损伤和发光等方面的多功能性而闻名。reported（Gd）是报道的低能中子俘获截面最大的元素之一，由于中子吸收而产生内部转换电子和γ射线。Gd-BTC薄膜（BTC = 1,3,5-苯三羧酸酯）的显影显示是通过喷枪沉积在Si和Al基板上，并通过轮廓测定法，拉曼光谱，EDX和X射线衍射进行了表征。还研究了这些膜的辐射损伤，热分解和中子吸收。将Gd-BTC薄膜附着到对内部转换电子敏感的CMOS器件（互补金属氧化物半导体）上，为了建造一个中子探测器。Gd-BTC / CMOS设备可以在存在γ射线的情况下选择性地检测中子，热中子的检测效率为3.3±0.1％，信噪比为1：1，非常适合获取图像。
