Energy level alignment in TiO2/metal sulfide/polymer interfaces for solar cell applications

The experimental energy level alignment has been determined for complete TiO2/metal sulfide/polymer interfaces using photoelectron spectroscopy and the results are compared to the function of solar cells.

STUDY ON GROUND STATE ENERGY BAND OF EVEN 114-124Cd ISOTOPES UNDER THE FRAMEWORK OF INTERACTING BOSON MODEL (IBM-1)

In this research, the ground state gamma ray bands of even 114-124 Cd isotopes are calculated using interacting boson model (IBM-1). The theoretical energy levels for Z = 48, N = 66–76 up to spin-parity 8+ have been obtained by using PHINT computer program. The values of the parameters in the IBM-1 Hamiltonian yield the best fit to the experimental energy spectrum. The calculated results of the ground state energy band are compared to the previous experimental results and the obtained theoretical calculations in IBM-1 are in good agreement with the experimental energy level.

Parametrization of Crystal Field Splittings of the 7Fj Levels in Eu3+ Doped Tetragonal Rare Earth Oxyhydroxides, REOOH :Eu 3+ (RE = Y and Lu)

The luminescence spectra of europium (3 + ) doped rare earth oxyhydroxides, REOOH :Eu3 + (RE = Y and Lu), were studied and analyzed at 77 and 300 K under UV and dye laser excitation. The observed 7F0_4 level schemes were simulated with the aid of the phenomenological crystal field theory. The descending symmetry method from C2v to Cs symmetry was used in the simulation. Good results were obtained with Cs symmetry simulation which yielded r.m.s. deviations of 6 and 7 cm -1 between the calculated and experimental 7F0_4 level schemes for YOOH:Eu3 + and LUOOH:EU3+, respectively. The C2v simulation was found inadequate to describe the experimental energy level schemes. The even rank crystal field parameters vary only slightly as a function of the host. Comparison with the corresponding values obtained for the monoclinic form of the Eu3 + doped RE oxyhydroxides reveals significant differences.
