Fabrication and photoluminescence of highly crystalline GaN and GaN:Mg nanoparticles

Facile Synthesis of New Full‐Color‐Emitting BCNO Phosphors with High Quantum Efficiency

“…The emission peak of the sample prepared at 800 8C has a relatively higher intensity as compared to the sample prepared at 700 8C, which is not unexpected since photoluminescent materials prepared at higher temperatures generally exhibit higher PL intensities because of increased crystallinity. [12][13][14] However, the sample prepared at 900 8C shows the lowest PL intensity of this set of samples, and the PL spectra measured for this sample is very different from that of samples prepared at 700 and 800 8C. A possible explanation for this phenomenon is that the carbon content in the sample evaporates at 900 8C, thus significantly changing the composition of the sample.…”

Ga2O3 and GaN nanocrystalline film: Reverse micelle assisted solvothermal synthesis and characterization

“…Due to its anisotropic and polar nature, GaN exhibits direction-dependent properties [12,13]. A number of physical and chemical routes were adopted previously in order to synthesis nanostructures of Ga 2 O 3 [5] and GaN [14,15]. However, there is no report on the preparation of Ga 2 O 3 and GaN QDs by microemulsion or reverse micelle.…”

Synthesis of rare‐earth activated AlN and GaN powders via a three‐step conversion process

“…Recently, various groups have demonstrated activator emission in bulk GaN powders. Blue emission was demonstrated by Ogi et al with their GaN:Mg powders [6], while green emission from Er 3+ activated GaN powders was observed by Wu et al [7]. Nyk et al also showed Eu 3+ and Tb 3+ emission separately in GaN host [8].…”
