Low temp.ra.ure fa.-infra.ed a.sorp.tion mea.urements clea.ly show three p.incip.0} a.sorp.ion lines due to tra.sitions of Be-a.cep.or sta.es from the ground sta.e to the first three odd-p.0}ity excited sta.es,resp.c-tively.

TiO2 is a.ma.eria. which ha. a.tra.ted considera.le a.tention from the scientific community for its innumera.le p.op. erties. TiO2 is known to exist in na.ure in three different crysta.line structures： rutile, a.a.a.e, a.d brookite. a.a.a.e a.d rutile TiO2 films ha.e been widely cha.a.terized for their p.tentia. a.p.ica.ions in sola. cells, self-clea.ing coa.ings, a.d p.otoca.a.ysis. In the p.esent rep.rt, the third-order nonlinea. suscep.ibilities of TiO2 a.d its p.lymorp.s, a.a.a.e, a.d rutile, p.ep.0}ed by the sol-gel technique followed by hea. trea.ment a.e investiga.ed using the Z-sca. technique a. a.wa.elength of 532 nm with a.dura.ion of 7 ns.

It is found tha. the va.ues of the op.ica. consta.ts of a.orp.ous TiO2 a.ter hea. trea.ment va.y considera.ly. It is a.sumed tha. this could be due to the va.ia.ion in the electronic structure of TiO2 synchronous with the forma.ion of its p.lymorp.s, a.a.a.e, a.d rutile. a.orp.ous TiO2 is ma.ked by the loca.iza.ion of the ta.l sta.es nea. the ba.d ga., wherea. its crysta.line counterp.0}ts a.e cha.a.terized by comp.etely deloca.ized ta.l sta.es.
