The role of type II FB (I):Tl+ defect in laser light generation and color image formation at the low coordination surface sites of AgBr: Ab initio calculations
منشور في 2006"…All relaxed excited states of the defect containing surfaces were deep below the lower edges of the conduction bands of the ground-state defect-free surfaces indicating that type II FB(I):Tl+ is suitable laser defect. The probability of orientational destruction of the two centers, attributed to the assumed saddle point ion configurations along the 〈1 1 0〉 axis, was found to decrease as the coordination number of the surface ions decreases. …"
