Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

open access: yesAdvanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Robust Multicast Device-to-Device Communication

2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS), 2018
Device-to-device (D2D) multicast communication can be employed in distributing popular content among similarly interested groups thereby reducing the load on the network. When the network multicasts a requested file to a cluster or group of users, some members of a cluster may not receive the sent data correctly and so may require re-transmission by ...

Device-to-Device Communications

2016
This chapter provides an account of the most significant areas of scenarios and applications relevant to Device-To-Device (D2D) communications. At first, a state of the art review is provided, with focus on the special technological challenges. In addition, integration initiatives with modern cellular technologies and standards are given.
