MADRID, SPAIN: A team of researchers from the National Research Council (CSIC) and the Akademie Ved Ceske Republiky (Academy of Sciences of the Czech Republic) has discovered a new type of inorganic material (no carbon) that can emit laser light in solution; it is a complex of boron and hydrogen. The study, published in the journal Nature Communications, shows that the new material has efficient and durable in the blue laser emission, a spectral region of interest in applications such as spectroscopy or processing of materials, among others.

In 1960 the first laser operation was achieved for 55 years and is still looking for materials that emit blue light efficient, tunable and stable manner, and that are cheap, easy to produce and versatile when it comes to process. “Currently there are several commercial materials are close to these requirements, although showing some practical drawbacks. In our study we present a solution that seeks to help overcome these limitations,” said Inmaculada Garcia-Moreno, CSIC researcher at the Institute of Physical Chemistry Rocasolano.

Although this is not a new material is the first time that the boron hydrides or boranes are used for this type of light. Specifically, work researchers have turned to solutions of anti -B 18 H 22. Of the materials known to date, which most resemble these compounds are organic dyes that emit laser light efficiently (energetic) and tunable (you can change the color of issue) but are easily degraded forcing renew the laser medium from time to time.

Studied material has a tensile strength greater than or similar to that of commercial dyes in the blue spectral region degradation. Thus, the number of times you need to change the liquid laser and new ways to solve problems of cost, labor risks for its management and environmental impact, as the solvents used are toxic and flammable opening is reduced.

Synthesizing new boranes that emit in other wavelengths (colors) is the next step CSIC scientists posed as this would open the door, for example, its possible application in dermatology to remove scars, tattoos or acne and to treating vascular lesions. “Much work remains to be done before these compounds make the leap to the commercial world but the scientific significance of this discovery marks a milestone in the history of the laser, since not many times when a new family of laser materials disclosed,” concluded Luis Cerdan, also CSIC researcher at the Institute of Physical Chemistry Rocasolano.
