文摘
- •
Room temperature based spectral shift mechanism was studied with a threshold current density of 42.28 kA/cm2.
- •
The PL peak intensity shifts towards the higher wavelength i.e red shift.
- •
The carrier density dependence conveys that the red shift of the spectral emission is due to band gap narrowing.
