Nanoco, which develops quantum dot lighting, saw its share price go dimmer after announcing losses had widened in the last year.

The firm was £4.35m in the red in the year to the end of July, from £3.22 the year before.

It posted a loss in terms of earnings per share of 1.8p, compared to 1.3p in 2011, saying there would be no dividend.

The loss came on revenues that were up to £2.95m from £2.64m the previous year.

The firm said the wider loss reflected costs associated with completing the company's Kilo Lab facility, together with higher staffing costs.

The firm also warned that it remained difficult to predict the exact timing and scale of orders particularly as it was seeing an emerging preference in the display industry towards its quantum dots being used in films.

Renewable Energy Generation, the green energy group, saw losses before tax narrow to £1.96m in the year to June 30th from losses of £2.98m the year before.

Revenue climbed to £12.1m from £9.8m the previous year.

Cash and equivalents at the end of the reporting period totalled £9.6m, down from £14.9m a year earlier. The group said it expects to be able to fund its construction programme without needing to raise additional equity.

Despite making a loss, the company has maintained its final dividend at 1.5p.

"This year has seen us over-achieve against our three-year target to commit £100m of investment in UK renewable projects," declared Andrew Whalley, Chief Executive Officer of the group.

"Alongside successful construction of energetic new sites, we have also made considerable progress with planning submissions over the past 12 months and are well-positioned to significantly expand our operating portfolio," Whalley added.
