Internal polarizations field which take place in quantum structures of group-III nitrides have an important consequence on their optical properties. Optical properties of wurtzite AlGaN/GaN quantum well (QW) structures grown by MBE and MOCVD on c-plane sapphire substrates have been investigated by means of photoluminescence (PL) and time resolved photoluminescence (TRPL) at low-temperature. PL ...

Despite the rapid development of the quantum well ~QW! infrared technology, the intrinsic properties of the QW infrared photodetectors ~QWIPs! have not been directly measured under the operating conditions of the detector. In this work, we introduce a characterization technique, which utilizes the surface corrugation to probe the absorption coefficient and the photoconductive gain of a QWIP und...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
