BACKGROUND We have previously proved that treatment of thick/deep infantile hemangiomas (IHs) with a long-pulse Alexandrite laser was clinically effective and safe. This article aims to investigate the efficiency of l...
The investigation of electrical properties in alexandrite (BeAl2O4:Cr3+) in synthetic and natural forms is presented in this paper. Alexandrite is a rare and precious mineral that chan...
Results of photoluminescence measurements for natural and synthetic alexandrite (BeAl2O4:Cr3+) are presented, where the samples are excited by the 488 nm line of an Ar+ laser, at different temperatures. The main issue...
In order to investigate optical properties of alexandrite, the present work deals with the influence of thermal annealing on optical absorption and luminescence spectra of natural samples. The exposure time to heat tr...
A new method DV-X_α-HF is proposed. The DV-X_α-HF study of the cluster (BeCrO_6)~7-is reported for the first time. The single-electron energy eigenvalues, the crystal field sep-aration parameter 10D_q and charge tra...
