Spectroscopic Characterization of Titanium Doped Sapphire.

Abstract

Titanium (III) in corumdum shows a short-lived (3.1 micro s) broad 2E - 2T2 luminescence around 740 nm, and a 10 times longer-lived 2A1 (4s)-2T2 centered around 410 nm. Both these broad-band emissions with large Stokes shift show prospects for tunable lasers. The absorption spectrum is studied in detail, and traces of titanium (IV) are shown not to be involved in the violet emission, in contrast to a parasitic absorption around 700 nm due to Ti (III, IV), like sapphire is blue due to Fe (II) Ti (IV) Fe (III) electron transfer bands. Keywords: Titanium, Iron.
