“…The spectrum of the product synthesized at a stoichiometric Si ratio of 0.5 (run 6) agreed with the spectrum of typical green-emitting ZSM that is based on the spin-forbidden transition from the lowest excited state 4 T 1 ( 4 G) to the ground state 6 A 1 ( 6 S) of 3d 5 electrons in Mn 2+ ion [31,32]. At Si ratios less than 0.5 (runs 1-5), VUV-PL intensities decreased, but the shape of the spectra were similar to that of product at the Si [27,30,33,34] increased as the Si ratio progressed. At Si ratios more than 0.64 (runs 9-12), two peaks in the VUV-PL spectra appeared at around 525 and 560 nm, respectively.…”

Fluorescence is increasingly used for in vivo imaging and has provided remarkable results. Yet this technique presents several limitations, especially due to tissue autofluorescence under external illumination and weak tissue penetration of low wavelength excitation light. We have developed an alternative optical imaging technique by using persistent luminescent nanoparticles suitable for small animal imaging. These nanoparticles can be excited before injection, and their in vivo distribution can be followed in real-time for more than 1 h without the need for any external illumination source. Chemical modification of the nanoparticles' surface led to lung or liver targeting or to long-lasting blood circulation. Tumor mass could also be identified on a mouse model. biodistribution ͉ in vivo optical imaging ͉ nanoparticles ͉ phosphorescent nanoparticles

“…Götz and Masson reported that the transformation of orthorhombic b-phase into a-phase commenced at 835 C as an exothermic reaction according to thermal analysis methods [39]. Leverenz et al reported that yellow-emitting b-phase and green-emitting a-phase were reversible by quenching at 1600 C and re-heating at around 950 C [40,41]. In subsequent literature, the orthorhombic b-phase registered as JCPDS no.…”
