Synthesis and optical properties of ZnO incorporated Tris-(8-hydroxyquinoline)aluminum

Preparation and Characterization of 8-Hydroxyquinoline Aluminum/Polypyrrole Core-Shell Composites

“…The formation of rod-like morphology in the Alq 3 material shows the homogenous shape and size. This indicates the homogenous mixture of the Al compound and HQ compound in the Alq 3 material [11]. Fig.…”

“…Besides, the prominent bands at ca. 1470 cm characteristic of O-H stretching vibration is observed [11]. Fig.…”

“…Therefore, in order to improve the stability and photoluminescence intensity of composites, we all considered using polymerization to synthesize composites. [11,12]. Herein, we report the synthesis of novel core-shell Alq 3 /PPy composites.…”

Optical properties of composite structure based on ZnO microneedles and Alq3 thin film

“…Our results correlate satisfactorily with the data reported in Refs. [10][11][12]14]. According to that data, compared with PL of pure Alq 3 and ZnO, PL of the composite sample based on ZnO and Alq 3 has higher intensities due to the processes of energy transfer between inorganic and organic materials.…”

“…In this situation, ZnO-based LEDs usually are fabricated by combining of n-type ZnO with a p-type semiconductor other than ZnO, for example, Cu 2 O, ZnTe, SrCu 2 O 2 , AlGaN, GaN or p-type conduction polymers [7,9]. To our knowledge, there are quite a number of publications devoted separately to ZnO and Alq 3 , while composite materials based on them have been studied by only a few research teams from India [10][11][12][13][14][15], China [16,17], Swiss [18], Republic of Korea [19] and Japan [20]. They consider different combinations of this composite such as amorphous or polycrystalline AlQ 3 or ZnO doped with ZnO [10][11][12] or AlQ 3 [13,14], composite nanowires [19], heterostructures [16,17,20], or AlQ 3 imbedded into porous ZnO [15,18], and enhancement of photoluminescence intensity of AlQ 3 and ZnO has been observed.…”
