Terbium-picrate triethylene glycol（EO3-Tb-Pic） complex was prepared in thin film and single layer device structure of ITO/EO3-Tb-Pic/Al, using spin coating technique. The UV-Vis absorption spectroscopy analysis was performed to evaluate the electronic molecular transition of the complex. The optical band gap, Eg estimated from the Tauc model revealed that EO3-Tb-Pic thin film exhibited a direct transition with Eg of 2.70 eV. The electronic parameters of the ITO/EO3-Tb-Pic/Al device such as the ideality factor n, barrier height Φb, saturation current Io, and series resistance Rs, were extracted from the conventional lnI-V, Cheung＇s functions and Norde＇s method. It was found that the evaluated parameters calculated from Norde＇s and Cheung＇s methods were consistent with those calculated from the conventional I-V method. In the double logarithmic I-V plot, three distinct regions based on the slope were identified, and the conduction mechanisms were discussed and explained. The mobility, μ value was estimated from SCLC region as 2.58×10^–7 cm2/（V·s）. This newly obtained lanthanide complex may be potentially utilized in electronic devices.

Objective:To identify the presence of acarine ectoparasites and determine whether there is any potential public health risk in Panti Forest Reserve,Johore,***:Trapping of animals and avifauna was conducted simultaneously along 5 expedition trails using 150 wire traps,10 harp traps and 30 mist nets for 6 consecutive nights.A total of 140 animals consisting of 7 species of birds,19 species of bats,6 species of rodents and 1 species of tree-shrew as well as 8 myriapods were ***:Infestation rates of ticks,mesostigmatid mites and chiggers on animals examined were 24.3%,28.6%and 27.9%,*** on bats was low(1.5%) and none occurred on *** of ticks extracted were at immature stages(78.9%). Genera of ticks on animals were Amblyomma,Dermacentor,Haemaphysalis and *** granulatus was the only species of licks identified from the *** of ticks under vegetation revealed 54%adults leading to identification of 3 species of ticks.A total of 7 species of mesostigmatid mites were found.6 species were on rodent,Maxomys mrifer and another one species,Laelaps nuttalli was found only on Leopoldamys *** sanguisugus was the only mesostigmatid found infesting *** genera of chiggers were *** this,5 genera were on rodents,4 genera on tree-shrews and 1 genus on a ***:A total of 16 genera,2 sub-genus and 14 species of acarine ectoparasites were found in this area. Findings of the survey demonstrate the presence of three spesies of acarine ectoparasites which have potential health risk *** granulalus,Laelaps nuttalli and Leptotrombidium deliense.
