Disclosed is a building blocks method for low-cost fabrication of single crystal organometallic perovskite materials with pseudo crystallized hole transporting material layer. This method uses self-assembled molecular monolayers SAM as building blocks. This approach enables creation of defect-free perovskite crystals with desired morphology and crystallinity in a controlled way. Additionally, the crosslinked molecular layers SAM play a role of hole transporting materials HTM and encapsulation against diffusion of metal atoms and gas molecules, thus enhancing the stability of the perovskite materials. This method is cost effective and can be scaled up.

Disclosed is a radiation detector including a thallium bromide crystal, and a first electrode and a second electrode facing each other with the thallium bromide crystal interposed therebetween. The thallium bromide crystal contains 0.0194% to 6.5% by mass of chlorine atoms based on a mass of the thallium bromide crystal.

A low cost, rapid, flexible radiation detector uses inorganic metal halide precursors and dyes that respond to self-quenching hybrid scintillation. Remote, high-contrast, laser sensing can be used to determine when exposure of the detector to radiation occurs (even temporally).
