The findings from this work show the importance of linking photosensitises such as phthalocyanines to metal nanoparticles for the enhancement ofsinglet oxygen quantum yield and ultimately the photodynamic effect.]]> Thu 13 May 2021 08:10:17 SAST ]]> On the growth and characterisation of AIGaN alloys for optoelectronic applications http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:26433 0.3. The possibility that Si could become a DX-centre in AlxGa1-xN was then investigated. However, Hall effect measurements showed that the Si activation energy increased in good agreement with the model of a shallow effective mass state donor, with no sudden increase in ED being observed up to x = 0.4. It was then suggested that the increase in the E1 and E2 activation energies, as well as the exciton localisation energies, could be due to the 9 7 valence band crossover, which occurs at roughly the same composition. However, due to the scarcity of reports on the valence band structure in AlxGa1-xN no conclusions could be made at this stage as to the effect of the 9 7 valence band crossover on the PL properties of AlxGa1-xN.]]> Thu 13 May 2021 05:42:11 SAST ]]> Rhodes University Research Report 2011 http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:566 Thu 13 May 2021 05:36:34 SAST ]]> A cross cultural study of eidetic imagery and short term memory http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:3141 Thu 13 May 2021 02:19:08 SAST ]]> South African anti-apartheid documentaries 1977-1987: some theoretical excursions http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:3484 Mon 14 Aug 2023 11:57:11 SAST ]]>
