Abstract: A nonwoven laminate, including a nonwoven layer including multicomponent staple fibres and a needled nonwoven layer including monocomponent staple fibres and multicomponent staple fibers, wherein the layers are bonded to each other by melt-bonding, and not by needling. The multicomponent staple fibers include a polyester component and a copolyester component and the monocomponent staple fibers in the needled nonwoven layer are polyester fibers. All fibres of the nonwoven laminate are polyester and/or copolyester fibers, and the needled nonwoven layer has a basis weight of 500 to 2000 g/m2, determined according to DIN EN 29073-1:1992-08. The nonwoven laminate has a bending force of at least 6 N, determined according to ISO 178:2019 for 2 mm deflection.

Abstract: Fast, bright inorganic scintillators at room temperature are based on radiative electron-hole recombination in direct-gap semiconductors, e.g. CdS and ZnO. The direct-gap semiconductor is codoped with two different impurity atoms to convert the semiconductor to a fast, high luminosity scintillator. The codopant scheme is based on dopant band to dopant trap recombination. One dopant provides a significant concentration of carriers of one type (electrons or holes) and the other dopant traps carriers of the other type. Examples include CdS:In,Te; CdS:In,Ag; CdS:In,Na; ZnO:Ga,P; ZnO:Ga,N; ZnO:Ga,S; and GaN:Ge,Mg.
