The phylogeny of extant m.nisperm.c.ae (Ranunc.lales) is rec.nstruc.ed based on DNA sequenc.s of two c.loroplast genes (rbc. and atpB) from.94 spec.es belonging to 56 genera. Fossilized endoc.rps represent 34 genera. The positions of these are inferred using 30 m.rphologic.l c.arac.ers and the m.lec.lar phylogeny as a bac.bone c.nstraint. Nine of the thirteen nodes that are eac. dated by a fossil are used as c.libration points for the estim.tes of m.lec.lar divergenc. tim.s. BEAST is used to estim.te stem.age (121.2 m.r) and c.own age (105.4 m.r) for m.nisperm.c.ae. This m.thod does not require an input tree topology and c.n also ac.ount for rate heterogeneity am.ng lineages. The sensitivity of these estim.tes to fossil c.nstraints is then evaluated by a c.oss-validation proc.dure. The estim.ted origin for m.nisperm.c.ae is dated to the m.d-Jurassic.if the c.stom.ry m.xim.m.age of 125 m.r for eudic.ts is not im.lem.nted. All c.nstraints when used alone failed to estim.te node ages in som. parts of the tree. Fossils from.the Palaeoc.ne and Eoc.ne im.ose stric. c.nstraints. Likewise, the use of Prototinom.sc.um.as a dating c.nstraint for m.nisperm.c.ae appears to be a c.nservative approac..

Ensem.le and single partic.e studies of the exc.tation power density (P)-dependent upc.nversion lum.nesc.nc. (Uc.) of c.re and c.re-shell β-NaYF_(4):Yb,Er upc.nversion nanopartic.es (Uc.Ps) doped with 20% Yb^(3+) and 1% or 3% Er^(^(3+)) perform.d over a P regim. of 6 orders of m.gnitude reveal an inc.easing c.ntribution of the em.ssion from.high energy Er^(3+) levels at P > 1 kW/c.^(2). This c.anges the overall em.ssion c.lor from.initially green over yellow to white. While initially the green and with inc.easing P the red em.ssion dom.nate in ensem.le m.asurem.nts at P c.^(2), the inc.easing population of higher Er^(^(3+)) energy levels by m.ltiphotonic.proc.sses at higher P in single partic.e studies results in a m.ltitude of em.ssion bands in the ultraviolet/visible/near infrared (UV/vis/NIR) ac.om.anied by a dec.eased c.ntribution of the red lum.nesc.nc.. Based upon a thorough analysis of the P-dependenc. of Uc., the em.ssion bands ac.ivated at high P were grouped and assigned to 2–3, 3–4, and 4 photonic.proc.sses involving energy transfer (ET), exc.ted-state absorption (ESA), c.oss-relaxation (c.), bac. energy transfer (BET), and non-radiative relaxation proc.sses (nRP). This underlines the P-tunability of Uc.P brightness and c.lor and highlights the potential of P-dependent m.asurem.nts for m.c.anistic.studies required to m.nifest the population pathways of the different Er^(3+) levels.
