FIELD: physics.
SUBSTANCE: radiation detector has an array of photodetector elements, having one or more photodetector elements, one or more display elements adjacent to the array of photodetector elements, light-reflecting material coating lateral sides and top side(s) or sides of said one or more display elements, wherein at least part of the light-reflecting material is a polymer with a refraction index of less than 1.5 and modulus of elasticity of less than 2 GPa and preferably less than 1 GPa.
EFFECT: reduced crosstalk between pixels.
