Ultraviolet radiation is widely used in biomedical practice. In some areas, its use is limited by the lack of sufficiently cheap sources of the desired spectrum and power. The prototypes of mercury-free cathodoluminescent ...

The time-resolved photoluminescence triggered by a ∼30 ps long exciting pulse centered at the time 154 ps was investigated. The use of long pulses allows one not only to trace the decay of multi-exciton complexes, but also ...
