“…The absorption maximum for all three compounds obtained from the PMMA matrix was within 3.1 to 3.3eV. It is shifted to the ultraviolet region compared to the original DMABI which holds the absorption maximum of 2.583eV [23].…”

“…The two-electrode corona poling setup described above has been successfully used for practical poling of polymer samples and acquiring NLO active thin films [5][6][7][8][9][10]. At the same time, uncertainty in control of the sample surface charge build-up is typical for a setup of the kind, and, therefore, the poling field strength remains unknown.…”

Chromophore Poling in Thin Films of Organic Glasses. 2. Two-Electrode Corona Discharge Setup In Part 1 of the article we provided description of the corona discharge physics and overview of the methods used for corona poling in thin organic films. Subsequent sections describe comparatively simple technical methods for poling the organic nonlinear optical polymers using a two-electrode (point-to-plate or wire-to-plate) technique. The polarization build-up was studied by the DC positive corona method for poling the nonlinear optical (NLO) polymers. The experimental setup provides the corona discharge current from 0.5 μA up to 3 μA by applying 3 kV - 12 kV voltage to the corona electrode and makes possible selection among the types of corona electrodes (needle, multi-needle, wire, etc.). The results of experimental testing of the poling setup show that at fixed optimal operational parameters of poling - the sample orientation temperature and the discharge current - the corona charging of polymeric materials can successfully be performed applying the two-electrode technique. To study the dynamics of both poling and charge transport processes the three-electrode charging system - a corona triode - should be applied.

“…Quantum chemical calculations indicate a large dipole moment of the DMABI molecule in the ground state (d o = 2.3 D) and a considerable change of this value in the excited state (d ex = 14.2 D). These molecules exhibit also second-order non-linear effects [14,15]. Among…”
