Influence of ZnS on the structural, morphological, optical and thermal properties of Polyindole for an emissive layer

FRET mechanism to enhance the quantum yield of the PCz/gC3N4 nanocomposite, an emissive material for OLED applications

“…Urbach energy measures the total localized tail area. Urbach energy ( E u ) was calculated by using the equation given below, 45 The Linear Urbach energy equation iswhere α 0 and E g are constants depending on the materials, h and ν are the Planck constant and frequency of the incident wavelength, respectively, and α is the absorbance coefficient of the material. In the plot of the linear Urbach energy ln( α ) along the Y -axis and hν along the X -axis, the inverse of the slope provided the Urbach energy of the material .…”

Synergistic Influence of FRET on a High Quantum Yield π- Conjugate Polycarbazole-ZnS Composite Thin Film

“…The Bode plot (ϕ vs frequency) also demonstrated the effective electron lifespan (τ) within the electrode/electrolyte transition. The following relationship may be used to calculate the effective electron lifetime value τ = 1 w max = 1 2 π f max …”

“…During the synthesis of ZnS, we used zinc nitrate hexahydrate, thiourea, and ethylenediamine. The ZnS synthesis process 16 is described in the Supporting Information.…”

“…The following relationship may be used to calculate the effective electron lifetime value. 16 w f On the Bode plot, the phase angle is higher than it is for pure polycarbazole, indicating that the PCZ exhibits improved electrochemical behavior. For PC, ZnS, and PCZ, the values of τ were 32.21, 38.35, and 43.48 ms, respectively.…”
