Abstract
One-dimensional nanostructures have been of great interest for photonic devices. In this talk I will give a review of the one-dimensional ZnO nanostructures for ultraviolet and visible regions. I will discuss earlier and last results regarding room temperature and low temperature spontaneous and stimulated emission. For lasers we will discuss both optically and electrically pumped lasers. For the LEDs particularly I will discuss the white light emission from LEDs. Substrates like graphene, paper, textile and semiconductors will be discussed. Finally, also results from other devices based on hybrid materials will be analyzed.
Highlights
Introduction and backgroundZinc oxide (ZnO) with its self-organized growth property combined with a direct wide band gap (3.34 eV), relatively large excitons energy (60 meV), and deep band emission covering the whole visible range constitute an interesting material for the development of different photonic devices
The growth of the ZnO NRs is achieved as follows: as a first step a conducting layer, typically a metal like silver is deposited to provide the bottom contact to the ZnO NRs
Zinc nitrate hexa hydrate (Zn (NO3)2.6H2O) was mixed with Hexamethyl tetra-mine (HMT) (C6H12N4) in equal molar concentartion and substrates were placed in the solution for four hours at 90 oC
